My guess is that you would need approximately 650 bricks. The math is as follows: 6 feet (72 inches) by 24 feet (288 inches) equals a total area of 20,736 inches. If your brick area is 4 x 8 inches (32 inches) you would need 648 bricks.
648 bricks to build the walk
The answer will depend on the size of the bricks, which are not standard.
the answer to this question is 648 Bricks.
You need 648 bricks. Convert 6 feet into 72 inches times by 24 feet converted to 288 inches which equal 20,736 square inches. A 4 x 8 inch brick is 32 square inches. Now take 20,736 inches and divide that by 32 which equals 648.
There is no information on the heights of either the bricks or the wall!
Approximately 648 bricks will be required. You have to revise that up a little bit for wastage.
You will require 61 bricks.
