4.4444. 144 square inches to a square foot.
There are 43,650 square feet in one acre. (There are 640 acres in one square mile and 27.878,400 square feet in the same area. 27,878,400 divided by 640 equals 43,650. To find how many square inches in an acre, multiply number of square feet by 144.
Assuming the bricks are 4 inches wide and 16 inches long. Then the area of one brick is 64 square inches = 64/144 = 4/9 square feet, hence to cover 640 square feet we need (640)/(4/9) = (640x9)/4 = 160x 9 = 1440
There are 12 inches in a foot, so 640/12 = 53.3333 feet.
6 inches = 0.5 foot27 cubic feet = 1 cubic yardVolume = (640 x 0.5) = 320 cubic feet = 1123/27 cubic yards = 11.852 (rounded)

To find out how many 3x6 tiles are needed to cover 800 square feet, first calculate the area of one tile. A 3x6 tile has an area of 18 square inches, which is 1.25 square feet (since 144 square inches = 1 square foot). Divide 800 square feet by 1.25 square feet per tile, which equals 640 tiles. Therefore, it will take 640 tiles to cover 800 square feet.
1 foot = 12 inches therefore 53 feet 4 inches = 640 inches 1 inch = 0.0254m (or 2.54cm) therefore 53 feet 4 inches (640 inches) = 16.256m
43560 square feet in an acre. 640 acres in a square mile.
80 feet x 8 feet = 640 square feet.
