The answer is 7.55 inches. There are two main ways to solve this. The first is to simply think about the problem logically. 7.55 inches is the only logical size of a souvenir Statue of Liberty. However, if you need to solve this with mathematics, I would begin by making everything the same unit. You can do this by multiplying all units of feet by 12. 151 feet = 1,812 inches, and 20 feet = 240 inches. Divide 1,812 inches by 240 inches to find the scaled-down size of the souvenir. 1,812/240=7.55.
