We are asked to find the volume of the given frustum.
Recall that the volume of a frustum is given by
Where h is the height, B₁ is the lower area and B₂ is the upper base area of the frustum.
The lower base area (B₁) is given by
The upper base area (B₂) is given by
Finally, substitute all the values into the above volume formula
Therefore, the volume of the frustum is 5096π cubic inches.
