The height of the rectangular prism is 5 cm
The rectangular prism has a base area of 16 cm².
Therefore,
V = 16h
where
h = height of the rectangular prism
Another box has a volume of 320 cm³ and holds 4 of the rectangular prism with no extra space.
Therefore,
4(16h) = 320
64h = 320
divide both sides by 64
64h / 64 = 320 / 64
h = 5
Therefore, the height of the rectangular prism is 5 cm
