2660 sq. ft.
One piece = 4 x 12 = 48 square feet 665 pieces cover (665 x 48) = 31,920 square feet 3,5462/3 square yards 0.001145 square mile (rounded).
For square footage (area) you only have two measurements. So a carpet 4 ft x 4 ft has a square footage of 16 square feet. And a carpet of 4 ft x 8 ft has a square footage of 32 square feet. Three measurements like 4 ft x 4 ft x 8 ft give you cubic footage, or volume. So the volume of a container that size would be 128 cubic feet.
32
You multiply them together - 20 x 4 = 80 square feet
14 x 4 = 56 square feet !
12 sq ft
13 x 4 = 52 square feet
