How many 4 by 8 inch bricks are needed to build a walk 6 feet wide and 24 feet long?
The way to calculate the number of bricks is to calculate the area of the walk and then divide by the area of a single brick. One very important point - the same units must be used for both areas (whether you choose inches, feet or anything else, it doesn't matter, you will get the same answer).The area of the walk is 6x24 square feet and, as there are 12 inches in a foot, this equals (6x12)x(24x12) square inches. This equals 20736 square inches.The area of a brick is 4x8 = 32 square inches.Dividing one by the other, the number of bricks required, N, is given by:N =20736/32= 648 bricks exactly.
