# Volume of a Frustum of a Regular Pyramid Calculator

The below online calculator helps you to calculate the volume of a frustum of a regular pyramid. A frustum of a pyramid is the portion of a pyramid which lies between one or two parallel planes cutting it. A right frustum is a parallel truncation of a right pyramid. In the below Volume of a frustum of a regular pyramid calculator, just enter the lower base area, upper base area and altitude to know its volume in mm^{3}, cm^{3}, m^{3}, in^{3}, ft^{3}, and so on.

### Example:

Calculate volume of a frustum of a rectangular pyramid having a altitude of 7 cm, lower and upper base area of 5 cm^{2} and 9 cm^{2}.

#### Solution:

V = (7/3)×(9+5+√(9×5))

= 48.3191 cm^{3}.
