Finally, divide the wall volume by the brick volume to get the number of bricks needed: 36 cu ft / 65.25 cu in = 36 / 0.03776 cu ft. = 953.39 bricks are needed, rounding up to 954. This calculation does not include the mortar joint between the bricks, but including it would complicate the example.

Let’s imagine we needed 100 bricks, but want to account for 12% waste (allowing for bricks breaking, etc.). We would calculate 12% of 100, which is 12, and add this value to the 100 bricks required. I would therefore require 112 bricks to account for this waste. NB: Brick wastage is commonly between 5% for hard bricks and up to 15% for softer
