> For all we know, the middle is just air and crumpled-up old newspaper.

I think this is the answer. I suspect the exhibit designers had a cool idea for a display, did a rough estimate of the area needed and then commissioned the exhibit builders to make the big metal-framed cube. Either they made an error in their calculation or the innate variability in the size of stacks of used bills threw it off. It's also possible the exhibit designer simply decided a bigger cube which filled the floor to ceiling space would be a better visual. Which would be unfortunate because, personally, the exhibit concept I'm more interested in is "$1M dollars in $100 bills fits in this area" not "Here's $1M in bills." The first concept is mildly interesting while the second is just a stunt.

Regardless of the reason it's off, I think it's most likely there's only $1M of bills in the cube. The folks responsible for collecting and destroying used bills tend to be exacting in their auditing for obvious reasons. So when the exhibit designers got $1M in used bills approved and released, that's exactly how much they got. It also stands to reason that they'd design the cube a little bigger than their calculated area requirement to ensure at least $1M would fit (along with some method of padding the interior) - although >50% seems excessive for a variability margin, so I still think it was an aesthetic choice or calculation error. Of course, one could do a practical replication to verify the area required with $10,000 in $1 bills.

Regardless, it's an interesting observation and a cool counting program to help verify.

daemonologist · 1m ago
The compression of the bills under their own weight might account for the excessive margin - a lone $100 bundle, even compressed by hand before measuring, probably takes up more vertical space than the ones in the cube.

> The folks responsible for collecting and destroying used bills tend to be exacting in their auditing for obvious reasons. So when the exhibit designers got $1M in used bills approved and released, that's exactly how much they got.

But who says that they didn't actually request $1.5M in used bills after doing the math of what it would take to make a cube. Or fill it up with $1M in used bills, and come back and make another request for $500k that also got approved...

ggreer · 3m ago
It could be that they measured a stack of bills sitting on a table, then did the math to make a metal frame to contain $1,000,000. But they didn't account for stacks compressing under the weight of higher stacks, and it wouldn't look as nice if the top part of the cube was empty.

Still, it does seem like it would be cheaper to rebuild the case than to add $500k to it. Maybe it's easy for the Fed to acquire more cash as long as it's guaranteed not to be spent.

johnfn · 27m ago
I think this is the most reasonable answer on the thread. As amusing as it is to see everyone come up with zany solutions, it is most likely something boring like this.
quantadev · 17m ago
Yeah, there's no way they piled the cash into a square on the floor and then measured it and then had the box made based on the measurements. They had the box made FIRST based on rough calculations, being sure to over-estimate it's size on purpose, knowing they can fill the interior with cardboard boxes as needed to space things out.
ninetyninenine · 17m ago
What’s the point of disseminating the technical reasoning behind it?

I think it’s better served to use this as an analogy of how the federal government handles money.

whatevertrevor · 4m ago
Because we still care about assigning sensible priors to whatever we think is the truth? You can use this to "analogize" how the feds handle money, but if they were actually careful with the money but a bit misleading on the space $1m would take, that's a different and less egregious error. Ignoring the space of potential possible explanations to make your analogy stronger is just confirmation bias with additional steps.

I'm half serious. Yeah I see the point. But more important to me is the analogy.

red_admiral · 8m ago
The economist's answer would be to offer to buy the cube for $1.1M. Tell them the extra $100k will fund building another cube plus expenses with spare cash left over. If you're right, pass GO and collect the payout.
goodcanadian · 21m ago
It's funny how all the comments seem to assume the conclusion is correct. I think it is far more likely that it is exactly $1M (plus or minus a couple of percent margin of error), and that the packing isn't uniform. It seems extremely unlikely to me that they would fuck it up so bad as to have $500k more in the box than claimed.

When you print money by the trillions, tracking every transaction becomes more important not less. I don't know about the exhibit, it is possible that this is not real money too.

in that case you would have to assume they stacked the money first, measured, then build a box to fit it

Maybe just my biased brain, but the title made it sound like they were half a million under, not over. In some way, this is how 1000 piece jigsaw puzzles will never be exactly 1000 pieces. As long as there's at least 1000, I think most people are fine, especially as an art piece. And of course as mentioned, there's the possibility that there's filler inside.

It would've been much worse if it was under though.

What??

ticulatedspline · 12m ago
Seems silly at first but in retrospect isn't that surprising to construct from requirements:

1: we want a big cube

2: has to have a million dollars

3: should be stacked neatly.

Given the bills are so evenly arranged on the lower surface there's only so many squares you can produce with the bills like that. 8x19 or 6x17 . 6x17 is noted as close to 1 mill but they only remove 2 stacks from the 100 side. so now it's not a cube, you'd come under if you trimmed it down to a cube.

so stacked flat seems 8x19 is the smallest square you can make for one side for a cube of cash that fits mil. so they did that and just filled it up.

It might be hollow, there's certainly a void. There's some comments about the border but you can clearly see that the bills don't go behind the border so the corners are squared in, which means there's probably a weird void of some sort because it's not really a normal cube.

somat · 10m ago
You need a cube that is a multiple of the width of a dollar on one side and a multiple of the height of a dollar on the other side. technically it needs to be a a multiple of the thickness of a dollar as well but that is so thin we can ignore it.

us dollar size: Width: 6.14 inches (155.956 mm) Height: 2.61 inches (66.294 mm)

How close over a million dollars can you make this cube?

I am a bit slow at math so still working on the ratios.

I wouldn't be surprised if the bills themselves are marked with specimen or something on the non-visible side. Maybe they're also artificially worn bills produced during bringup or testing.
burnt-resistor · 35m ago
I agree. The "money" probably has the shape and appearance of money, but isn't legal tender out of concern risk management and theft.

The cube is almost certainly hollow, to cut weight and cost.

It's the idea of what a cube of $1m would look like. It should at least fulfill that requirement faithfully.

This felt like the most obvious explanation to me as well. Maybe the artist's vision for it was a solid cube of cash, but it ended up needing a structure inside to support the thing.

So many reasons this might be exactly $1,000,000 but not sum up on the outside.

That said, this is also something I would have spent way too much time overthinking, so I thoroughly enjoyed reading the blog post.

What is the point in making a display like this at all in the first place, but making it either under claimed or over filled?

Who gets anything out of giving people the wrong idea about what $1m would look like?

If you are commissioning the thing to be built, why might you want it to either contain more than $1m, or be hollow and larger than what $1m really is? What purpose does an incorrect display serve? A correct display already serves almost no purpose in the first place, now make it incorrect.

None of the reasons I can think of would seem to apply here:

Disinformation.

Advertizement.

Art, where the artists point was to make it wrong and never tell anyone.

Simple goof up? This one is at least plausible. Someone estimated wrong, got a local shop to build an expensive cube(1), well we got the cube we got, fill it and get the display up.

(1) That will have to be quite thick polycarbonate or glass, not cheap. In fact, that right there might expose that there is at least some kind of fakery inside, if the glass is not at least as thick as the aluminum frame, then it's not strong enough, neither is the frame for that matter if it's what it looks like. So if the glass and frame are as thin as they look, then there is some kind of internal skeleton.)

Maybe there is some other significance we've lost since it was built. Maybe the $1m was never the interesting point originally. Maybe instead the dimensions or maybe weight of the cube were the interrsting thing, and this is really something like "1000 gallons of $1 bills" and that just hsppens to come out to 1.55m.

Since the rows counted were not uniform, why assume all 19 under each of them is? As such, it wouldn't have to be hollow, but doesn't have to be neatly packed in the center, either.

quickthrowman · 17m ago
I spend more time counting things than most people. I use the ‘Count’ tool in Bluebeam Revu (an architecture/construction pdf editor) when doing material takeoffs for construction estimating. You need to do a lot more than just count when doing a takeoff, so there really isn’t much use for a counting specific tool in my industry.

Bluebeam Revu can also do visual counts for specific symbols/images provided the drawings aren’t too busy, that is one use of AI I would like to see (automated takeoffs) so I don’t have to click thousands of light fixture symbols every year. One problem is that construction drawing are 2D and height information isn’t always present so measuring distance and accounting for rise and drop is difficult to automate, I use google maps street view frequently to gather height info (calibration is based off a standard commercial door at 80” x 36” or a CMU at 8” tall) if I don’t visit a site. Due to this and other factors, I think accurate construction estimating will be difficult to automate completely with LLMs, but the process will definitely be sped up by them.

counting things are a huge intellectual blind spot. For some reason, when people hear a figure, they accept it as gospel.

sums, averages, population, budgets, spending, rates.

Counting things is time consuming and error prone. Ask a casino. You can have 3 people count something and come to a different figure off by a few percent.

Seriously if someone says there's $1m in there, who is going to second guess? Thankfully this guy did.

People, as a group, trust numbers. Individuals, often, do not.

Pick any industry which revolves around something, I assure you there is a child-industry dedicated to providing the technology and infrastructure to count the things.

Heck, accounting, as a general purpose, applies to every profession, profession, is at its core, focused on counting things.

Hopefully this doesn't come across as argumentative. Your comment caused me to reflect on how you're right, we trust so much when it comes to numbers people tell us. But at the same time, we don't as evidenced by the vast amount of industry we dedicate to counting all that we do, whatever it is.

toast0 · 59m ago
A quick look around says commercially available bill counters count around 1000 bills per minute. Low cost counters have batch sizes of around 200 bills. Larger capacity counters are available.

Assuming the process keeps a single counter running continuously, it would be 1000 minutes, not quite 17 hours of work to do a single pass counting with one counter. There's a maintenance interval though. Some of the counters will scan serial numbers, so you could probably confirm you saw 1 Million distinct serial numbers while scanning. Multiple counters in parallel would reduce the wall clock time, of course. And you might want to do multiple counts, sometimes bills stick.

You could also count the number of straps and take a random sample to count. While counting the straps, you'd probably notice any grossly miscounted straps. If any of the sampled straps are wrong, you would presumably increase the sample rate to confirm. Weighing groups of 10 straps is probably faster than counting, but I don't know how sensitive it would be (depends on how consistent weights of the strapping material is, as well as weight of circulated bills).

I can't help wondering how big a cube you'd need to fill it with 1 million $1 coins.

43x43 piles of 541 coins each make 1000309 coins with a pile height of 541*2mm = 1.082m, while the width would be somewhat less than 43*26.5mm = 1.1395m with a hexagonal packing.

So just over 1m cubed, a little smaller than the bill version. But at 8100 kg, tons heavier.

Why in the world would you use KaTeX to write a number that is just being used as a number, not part of a mathematical formula? But, if you must, at least use some tricks to make the spacing work correctly: since TeX treats `,` as `mathpunct`, you need to use something like `\$1{,}000{,}000` (or change its catcode) to get something that renders as a plain old non-KaTeXed "$1,000,000" would.

In case you wondered, $1M in cash ($100 bills) weigh approximately 22 pounds (about 10 kilograms).

Last week I was watching that episode of Better Call Saul where he carries $7M throughout the desert for 36 hours, and realized his bags were supposed to get ripped 4 minutes into the process.

--

Calculation by Claude:

Here's the calculation:

A single US banknote weighs about 1 gram regardless of denomination.

So 70,000 bills × 1 gram = 70,000 grams = 70 kilograms = 154 pounds.

That's quite heavy - equivalent to carrying around a large person!

Those 70,000 bills would also represent $7 million in cash

* edit corrected the pounds calculation

Your answer is incorrect. You asked Claude to calculate $7M, which netted 154 pounds, but you then divided it by 10 instead of 7 to get the weight of $1M.

Further, it's quite irrelevant here, as the display involves $1 banknotes, not $100 bills. The correct answer, without the need for an LLM, is: 1 million bills times one gram = 1 million grams = 1,000 kg = 1 metric ton.
