The measure of the brick wall in inches is given by 14.5 x 12 by 5.5 x 12 by 0.5 x 12 = 174 by 66 by 6
Total volume of the brick wall is given by 174 x 66 x 6 = 68,904 cubic inches.
Volume of each brick = 6 x 4 x 2 = 48 cubic inches.
Therefore, number of bricks needed is given by 68,904 / 48 = 1,435.5 bricks.
