Question

James is using cement to make a new sidewalk and new steps. He will make rectangular sidewalk that is 8 feet long,4 feet wide and 0.25 foot thick what is the volume in cubic feet,of the cement used to make the sidewalk

Answer 1

Volume of a rectangular prism = w * h * l

w = width

h = height

l = length

In our instance,

w = 4ft

h = 0.25ft

l = 8ft.

Plug these numbers into our volume formula.

V = 4ft * 0.25ft * 8ft.

Multiply these numbers together.

V = 8 cubic feet

The volume of the cemet used to make the sidewalk is 8 cubic feet
