a cereal box can hold 144 cubic inches of cereal. if the box is 8 inches long and 1.5 inches wide how tall is the box?
Andreas93 [3]
The volume of a rectangular prism is simply length * width * height.
Therefore, all we have to do to find the height of the cereal box is divide the volume by the width and the length.

144 / 8 = 18

18 / 1.5 = 12

The cereal box is 12 inches tall.
Hope that helped =)
