To determine how many 16x16 inch blocks are needed for a 10x10 foot patio, first convert the patio dimensions to inches: 10 feet equals 120 inches. The area of the patio is 120 inches x 120 inches, which equals 14,400 square inches. Each 16x16 inch block has an area of 256 square inches. Dividing the patio area by the area of one block, you need 14,400 / 256 = 56.25 blocks, so you would need 57 blocks to cover the patio.

A cubic yard of gravel will cover 81 square feet at 4" of thickness. Multiply the width of the patio by the length of the patio to get your square footage. Gravel is usually sold by the cubic yard.

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.
To determine how many 16x16 pavers are needed for a 5x5 patio, first calculate the area of the patio and the area of one paver. The patio area is 5 feet x 5 feet = 25 square feet. Each 16x16 paver covers 2.67 square feet (16 inches = 1.33 feet, so 1.33 x 1.33 ≈ 1.78 square feet). Dividing the patio area by the paver area, you need approximately 10 pavers (25 ÷ 1.78 ≈ 14). Therefore, you would need about 15 pavers to cover the patio area completely.
12" x 12" = 1 square foot, so you need 452 of them.
12 x 12 blocks (assumed as 12 inch x 12 inch) That means the blocks are 1 square foot each Hence to cover 240 square feet area, you would need 240 blocks
