For example, to count a lot of money you can see how big of a stack 100 $1 bills makes, then see how big of a stack of $1 bills you have (or how many stacks that size you can make).

For example, to count a lot of money you can see how big of a stack 100 $1 bills makes, then see how big of a stack of $1 bills you have (or how many stacks that size you can make). Or you could weigh 100 $1 bills, and then weigh the whole pile. Chemistry 1110/1210 Dr Eric E.
