Planning & EstimatingQuestion 595 of 700
A floor is 14 ft by 16 ft and will be covered with 12-inch by 12-inch tiles. Adding 10 percent for waste, what is the MINIMUM number of tiles to order?
a.224 tiles
b.246 tiles
c.247 tiles
d.202 tiles
Explanation
Floor area = 14 x 16 = 224 sq ft. Each 12x12 tile covers 1 sq ft, so 224 tiles net. Add 10 percent waste: 224 x 1.10 = 246.4, round up to 247 (c). Option (a) omits waste. Option (b) rounds down instead of up. Option (d) subtracts waste instead of adding it.
