If a man is wallpapering a room 9ft by 9ft by 9ft high. How many square feet of paper will he need if there are 93ft^2 of openings in the room? How do i solve for the answer
Assume that only the four 9 ft by 9 ft walls are to be papered. Each wall will require (9 ft)^2 sq ft of paper, or 81 sq ft of paper. Multiply that by 4 (since there are four walls): 324 sq ft. Now subtract 93 sq ft from 324 sq ft to obtain the answer to this problem.
