Find the area of each 4" by 8" brick.
A%5Bb%5D+=+4%2A8
A+=+32sq.in.
Now find the area of the walk, but first convert the feet to inches by multiplying each dimension by 12" per foot.
6ft. = 72"
24ft. = 288" Now find the area.
A%5Bw%5D+=+72%2A288
A%5Bw%5D+=+20736sq.in.
To find the number of bricks required, divide the area of the walk by the area of a brick.
20736%2F32+=+highlight%28648%29bricks.
