You are installing a brick sidewalk. the brick portion of the sidewalk will occupy an area of 100 feet long by 4 feet wide. each brick will occupy an area 8 inches long by 4 inches wide. what is the minimum number of bricks you will need to build the sidewalk?

1,800 bricks are needed

Step-by-step explanation:

First convert the Length and width of the sidewalk into inches

Entire Sidewalk: L= 100x12 =1200in and W= 4 x 12 = 48in

Then we know Area = LxW, so we will do this for both the sidewalk and the brick.

Area of sidewalk: 1200 x 48 = 57600

Bricks ( no need to convert since the measurements are already in inches): 8 x 4 = 32

Now we will divide the area of the entire sidewalk by the area of a single brick to find out how many bricks you need to complete the whole sidewalk:

57600/32= 1,800 bricks
