what is frustum?

Expert Answer:

In geometry, a frustum is the portion of a solid - normally cone or pyramid, which lies between two parallel planes cutting it.

The volume of a frustum is the difference between the volume of the cone (or other figure) before slicing the apex off, minus the volume of the cone (or other figure) that was sliced off:

where h1 and h2 are the perpendicular heights from the apex to the planes of the smaller and larger base, B1, B2 are the areas of the two bases.
