How many 16 x 16 sq inch tiles are needed for 80 sqfeet?

Answer 1

16 x 16 inch tiles are actually (1 and 1/3) x (1 and 1/3) feet tiles which turns out to have an area of (4/3) x (4/3) = 16/9 square feet. So you want to cover 80 square feet. The number of tiles required is (80) / (16/9) = (80) x (9/16) = 45 tiles
