To determine the number of blocks needed to build a 2-foot high wall that is 10 feet long, you first need to know the dimensions of the blocks. Assuming standard concrete blocks are 16 inches long and 8 inches high, each block covers 1.33 square feet. The wall's area is 20 square feet (10ft x 2ft), so you would need approximately 15 blocks (20 square feet ÷ 1.33 square feet per block) to complete the wall.
