How do I figure out how many hollow blocks I need?

After you have found the square footage of both your wall and your block, determining the number of blocks you need is as simple as dividing the wall square footage by the block square footage. If you’re using a standard 16″ x 8″ x 8″ block, find the number of blocks needed by dividing the wall square footage by 0.89.

How do you calculate blocks?

Measure the length and height of the block in inches and then substitute the values in the equation square feet of block = (length of block x height of block) / 144. For example, a standard cement block measures 16 x 8 inches, so it covers 0.89 square feet — (16 x 8) / 144 = 0.89.
