Question

The volume, V, of a rectangular prism is determined using the formula , where l is the length, w is the width, and h is the height of the prism. Carltren solves for w and writes the equivalent equation w = .
Using this formula, what is the width of a rectangular prism that has a volume of 138.24 cubic inches, a height of 9.6 inches, and a length of 3.2 inches?

Answer 1

Formula is: V = l * w * h
w = V / l * h

Substitute their values, 
w = 138.24 / 9.6 * 3.2
w = 138.24 / 30.72
w = 4.5 in

In short, Your Answer would be 4.5 inches

Hope this helps!
