A piece of paper is 0.05 inches thick. Each time the paper is folded into half, the thickness is doubled. If the paper was folded 12 times, how thick in feet would the folded paper be?
- 10.24
- 12.34
- 17.10
- 11.25
Answer
C. 17.10
Solution
The thickness doubles each fold: 0.05 × 212 = 204.8 inches = 204.8/12 = 17.10 ft.
