Question

How many Radio Flyer wagons would it take to carry 50 million dollars in 10's, stacked no more than 3 ft high?

Answer 1

The dimensions of a radio flyer wagon are 36"x17.5", and we are limiting ourselves to 36" of height.  A $10 bill measures about 6"x2.5", so if we lay the bills long ways, we can lay 6 down and 7 across, hence a layer that is made up of 42 $10 bills, or $410.

Since a bill is about the same thickness as a sheet of paper, we can estimate that 2" would have 500 bills (about the thickness of a ream of paper).  So, 36"/2=18, and 18x500 would be 9000 bills in 3 feet of height, or $90,000 per stack.  Since we have 42 stacks, 42x90,000=$3,780,000 per wagon.

Now, we take the $50 million and divide it by $3,780,000, and we get 13.22 wagons, so you will need a total of 14 wagons.
