Room area
A = length × width
15 × 12 = 180 ft²
Add extra for waste
A × (1 + waste ÷ 100)
180 × (1 + 10 ÷ 100) = 198 ft²
Boxes: divide by the coverage per box, round up
boxes = ⌈flooring ÷ coverage⌉
⌈198 ÷ 20⌉ = 10
How it works
Area = length × width; flooring = area × (1 + waste); boxes = flooring ÷ coverage per box, rounded up
