# Pyramid frustum's volume (n-sided regular polygon bases)

## Description

A pyramid frustum is the portion of a pyramid that lies between two parallel planes cutting it. The volume of a pyramid frustum, whose bases are n-sided regular polygons, is related with the length of the sides of the two bases and the height of the pyramid frustum.
