6'x24'=144 square feet a square foot is 144 square inches so you take 144*144=20,736 square inches each brick is 4"x8"=32 square inches
so 20,736/32=648 bricks if none are messed up
There is no information on the heights of either the bricks or the wall!
You don't say how high the wall is.
Amount of bricks needed: 12(6*24)/(4*8) = 54
A single layer will require 144 bricks.

Assuming you actually require 24 feet long and 6 high as a 6 wide wall will be only 4 inches high. The bricks required without cutting contingency is 803
