Ok so for this question I have this so far but I don’t know how to go around approaching the last question

A $1bill weighs approximately...?(state weight of $1 bill.) So the weight of the national debt in $1 bill would be...(state weight of debt.) this is approximately... (make comparison to Some object.)

This is what I have so far A $1 bills approximately weighs 1 gram. In order to find the weight of the national debt in $1 bills I took the weight of the dollar bill and multiplied it by the national debt. 1 gram*$23 trillion=23,000,000,000 kilograms. So the weight of the national debt in dollar bills would be 23,000,000,000 kilograms.

I just need help with putting the weight into prospective a way that we would look at that as say oh wow that weighs a lot and compare it something but I don’t know how to approach it.

three Empire State Buildings would weigh about a billion kilograms

so the debt is about 70 Empire State Buildings
