Let B = number of bricks, L = length of wall, and H = height of wall.
B = (L / 6 in.) x (H / 3 in.)
The total number of bricks equals the number of bricks in one row multiplied by the number of bricks in one column. The number of bricks in one row is the total length of the wall divided by the length of each brick (L / 6 in.). The number of bricks in one column is the total height of the wall divided by the height of each brick (L / 3 in.). The total number of bricks depends on the height and length of the wall.
For example: If the wall was 25 ft (300 in) long and 5ft (60 in) high, the number of bricks would be: (300/6)x(60/3)=50x20=1000 bricks
