64 tiles for a square shape of 140 square feet
each tile equals 18 in x 18 in = 324 sq in
140 sq ft = 140 x (12x12) = 20160 sq in
20160 sq in : 324 sq in = 62.222 tiles
sq root of 62.222 = 7.888 tiles per side
so you will use 8 tiles per side and will have a leftover of .112
You will need at least 32 square yards of carpet to cover that area.
The answer depends on the measurement units used for 18x18.
13' x 15' (195 square feet) = 21.67 square yards of carpet needed.
28' x 14' (392 square feet) = 43.5 square yards of carpet needed.
18x18 what? 18 feet x 18 feet? 18 microns x 18 microns?
400 square yards. This is because there are 9 square feet in a square yard, and there are 3600 square feet of carpet needed to cover the 60' x 60' floor.
184.08 square feet is needed.
784 square feet requires a minimum of 87.1 square yards of carpet.
