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.
