Question

PLEASE IM DESPERATE Jamie wants to put tiles on the walls and floor of his room (but not on the ceiling). The length of his room is 10 feet, the width is 14 feet, and the height is 12 feet. If each tile is 1 foot long and 1 foot wide, how many tiles will Jamie need?
A. 856
B. 716
C. 348
D. 168

Answer 1

The answer is letter B

Answer 2

Number of sq ft. for floor = L*W = 10*14 = 140

Number of sq ft. for walls = 2*L*H+2*W*H = 2*10*12+2*14*12 = 576

Each tile is 1 sq ft. (L * W = 1), so Jamie would simply need the Number of sq ft. for floor + Number of sq ft. for walls, which equals B) 716 tiles.
