How many 4 by 8 bricks to cover 792 feet?
792 feet is a measure of length, not area. Therefore the width
of the bricks is irrelevant. The question is simply about the
number of 8-inch bricks that, when lined up, form a line that is
792 feet long.
The answer is 792*12/8 = 1188 bricks.
This assumes that 1187 thicknesses of cement between the bricks
have no effect!
