Asher began working through the problem using the steps. His work is shown. 1. Write the formula.

V = lwh

2. Substitute for the known values.

210 = l(3)(5)

A prism has a length of l, width of 3 feet, and height of 5 feet.

A prism has a width of 3 feet, a height of 5 feet, and a volume of 210 ft3. Which equation shows the length of the rectangular prism?
l = (StartFraction 210 Over 3 EndFraction) 5
l = StartFraction 210 Over 15 EndFraction
l = 210(15)
l = (StartFraction 210 Over 3 EndFraction) 3
