# Octagonal Pyramid Volume Calculator

Calculator to find the volume of the octagon pyramid. Please enter the side length (s) and pyramid height (h) to find the volume.

### Formula

**volume of an octagonal pyramid = (ba*h) / 3 **

where

ba is the base area of the pyramid and

h is the vertical height from the center of the base to the apex.

** base area (ba) = 2 x s ^{2}(1 + √2)**

Where

s is the side length.

The octagonal pyramid has **total nine faces** where **eight are triangular faces** and **one face is a regular octagon**. The octagonal pyramid also has **23 edges** and **nine vertices**.

Any pyramid having regular polygonal base of n sides will have n+1 faces and vertexes.
