You can put this solution on YOUR website!

First we shall convert 100ft%5E2 into square inches.
12in=1ft
So, 1ft%5E2=144in%5E2
Therefore, 100ft%5E2=14400in%5E2.
Area of the brick = Length+%2A+Width+=+4in+%2A+8in+=+32in%5E2
Number of bricks required to cover 14400in%5E2 is14400%2F32+=450.
So, you need 450 bricks.
