How many 8X8X16 concrete blocks would be needed on an 800 square foot wall?

To determine how many 8X8X16 concrete blocks are needed for an 800 square foot wall, first, we need to calculate the area covered by each block. The dimensions of each block are 8 inches by 8 inches by 16 inches.

While the blocks have three dimensions, for estimating the number of blocks needed for a wall, only the face area is relevant—that is, the area that will be exposed once the blocks are laid. The face area of an individual block can be calculated as follows:

1. Convert the dimensions of the block from inches to feet. Since there are 12 inches in a foot, the dimensions are:

• 8 inches = 0.67 feet (8/12)

• 16 inches = 1.33 feet (16/12)

2. Now, calculate the face area of one block:

• Face area = height x width = 0.67 feet x 1.33 feet ≈ 0.89 square feet.

Next, to find out how many blocks are required for the 800 square foot wall, divide the total wall area by the area of one block:

• Number of blocks = Total wall area / Area of one block =
