Problema Solution

The volume of a rectangle is 70 square feet. The height is 5 feet. The width is 2 less than the height. What is the length?

Answer provided by our tutors

We assume that the volume of a right rectangular prism 70 cubic feet:

V = 70 ft^3

H = 5 ft

W = H - 2

W = 5 - 2

W = 3 ft

L = the length

Since V = LWH we have:

L*3*5 = 70

L = 70/15

L = 4.67 ft

The length is 4.67 feet.
