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.
