ALGEBRA UNIT 3 1) HW DAY 9 LITERAL EQUATIONS Steve’s pets world sells aquariums that are rectangular prisms. The volume V of an aquarium is given by the formula V=Lwh where L is the length, w is the width, and h is the height. Solve the formula for h. Use the rewritten formula to find the height of the aquarium shown, which has a volume of 5850 cubic inches.
