Volume (v)


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


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 s2(1 + √2)


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.
