The dollar bills have a slight hollow indent, so you can’t just model them as a solid prism of ABS. I assume is the question here. You might be off by about 15%
The part pictured here seems to be 3069px7 with the base color incorrectly set to white. In any case, it’s 3069, the standard 1x2 tile. Thanks to the folks at LDraw who have modeled every Lego brick in detail (because of course people have done that), we get a volume of 303.8mm³, with a bounding box size of 408.6mm³, for a density of about 74%. But, Bricklink can just directly tell us the mass of a 1x2 tile is 0.26g, so the total mass is 10.5 metric tons.
What do you mean bulk density?

Of course someone has just published a table with all know masses of all lego pieces ever
That’s exactly the weight value I used in my original calculation :)
I used the weight value on bricklink.com which I assume is correct :)
Bingo.
In anything that does not perfectly stack, you have to assume a bulk density (density that accounts for porosity)
This is common in soil science since soils are only 50% solid.
