How to Calculate Concrete Blocks Needed

To calculate the blocks needed for the wall, first calculate the wall area need to cover.
Wall area is calculated length by width, for example, if the wall length is 5 feet, the length is 8 feet, then the area is 5 x 8= 40 feet².
or 40 x 144 = 5760 inches².
Choose your preset block size, if the block size is 16" x 8",
the area of the block is 16 x 8= 128 inches². Divide the wall area by block area, 
5760 inches²/ 128 inches² = 45 blocks.
