Question 1023681: Joe wants to wallpaper the four walls of his bedroom. The room is rectangular and measures 10 feet by 14 feet. The ceiling is 9 feet high. A roll of wallpaper at the store is 2 feet wide and 40 feet long. How many rolls should he buy? Wallpaper is hung ceiling to floor ignore doors and windows.

10 x 14 means a total perimeter of 48 feet (all the way around 4 walls)
48 ft x 9 ft high is 432 sq ft
A roll is 2 x 40 or 80 sq ft, so 5 are 400 sq ft, and not enough. 6 are needed.
