Determine the number of square inches of the blocks surface

Multiply 30 inches x 24 inches = 720 square inches per block

NOW find the number of square inches in an area 8 foot x 10 foot

Multiply 8 foot x 10 foot = 80 square feet

To find the square inches of a square foot, you multiply 144 inches (12 inches by 12 inches = 144 inches) by the number of square feet, thus,

80 square feet x 144 square inches = 11,520 square inches

In order find the number of blocks you will need to cover the area,

Divide the number of square inches of area to be covered by the number of square inches per block

11,520 square inches divided by 720 square inches per block = 16 blocks needed to

fill an area 8 foot x 10 foot.
