Question

A path is 3 feet wide and is paved with square bricks that are three inches wide. how many bricks wide is the path

Answer 1

Width of walk is 6 ft., or 6 x 12 = 72 in. Width of each brick is 4 in. Number of bricks that can be fitted along the width is 72 / 4 = 18.

Length of walk is 24 ft., or 24 x 12 = 288 in. Length of each brick is 8 in. Number of bricks that can be fitted along the length is 288 ÷ 8 = 36. 

18 x 36 = 648 bricks

Answer 2

Answer:

W = weight = 5.76 lbs

x = length = 8 in

y = width = 2.25 in

z = height = ?

 

D = density = 0.08 lbs/in3

 

D = W/(xyz) ⇒

 

z = W/(Dxy) = (5.76 lbs) / [(0.08 lbs/in3)(8 in)(2.25 in)] = 4 in

 

V = xyz

 

Just plug in the numbers to get V in units of in3.
