Answer:
24 inches cubed
Explanation:
The volume of a rectangular prism is given by the following formula:
Volume = Length * Width * Height
The volume of a pyramid is given by the following formula:
Volume = (1/3) * Length * Width * Height
So the volume of the prism is 3 times the volume of the pyramid.
If the volume of the prism is 72 in3, we have that the volume of the pyramid is 72/3 = 24 in3
