Question 74394
(32)(8)=256 feet is the area of the wall
(16)(8)=128 inches is the area of one masonry block.
You must take 256 feet times 12 inches so that both measurements are the same unit. (256)(12)=3072 inches in area for the wall.
Now divide 3072 by 128. The answer is 24, which means that you would need 24 masonry blocks.
