To determine how many patio stones are needed, first convert the dimensions of one stone from inches to square feet. A 24-inch by 24-inch stone is 2 feet by 2 feet, giving it an area of 4 square feet. Dividing the total patio area of 480 square feet by the area of one stone (4 square feet) results in 120 stones needed for the patio.
Gee, a square foot is 12x12, difficult problem.

To calculate the number of 12x12 patio stones needed for a 10'x14' patio, first find the area of the patio: 10 feet x 14 feet = 140 square feet. Each 12x12 stone covers 1 square foot (since 12 inches x 12 inches = 1 square foot). Therefore, you would need 140 stones to cover the entire area.

Assuming the 12x12 bricks are 12 feet on each side, those are 144 square feet. The patio itself is 76 square feet. Unless you made a typo, not even one of those bricks is going to fit on the patio; you end up with about 0.5278 bricks.

To calculate the area of the patio in square inches, we first convert the dimensions to inches (12 ft = 144 in, 14 ft = 168 in). The patio's area is therefore 24,192 square inches. Each 8-inch paving stone covers 64 square inches, so divide the total area by 64 to find that you'll need 378 paving stones to pave the patio.
12" x 12" = 1 square foot, so you need 452 of them.
