Planning & EstimatingQuestion 596 of 700
A room is 15 ft by 18 ft and will get laminate flooring. Each box covers 20 sq ft, and you add 10 percent for waste. What is the MINIMUM number of full boxes to buy?
a.14 boxes
b.13 boxes
c.27 boxes
d.15 boxes
Explanation
Floor area = 15 x 18 = 270 sq ft. Add 10 percent waste: 270 x 1.10 = 297 sq ft. Boxes = 297 / 20 = 14.85, round up to 15 (d). Option (a) ignores waste (270 / 20 = 13.5, round to 14). Option (b) ignores waste and rounds down. Option (c) uses a 10-sq-ft box.
