Pentagonal Pyramid Base Length Formula

In geometry, a pentagonal pyramid has a pentagonal base upon which five triangular faces are erected to meet at a point. It has 5 faces and 10 edges. Like any pyramid, it is self-dual. Given here the pentagonal pyramid base length formula to find the base edge. The base length is calculated by multiplying number 6 with the volume of the pyramid, and then diving the answer with the multiplication of 5 with height and apothem length of the pyramid.


b = (6 x v) / (5 x h x a)


b = Base Length
v = Volume of the Pyramid
h = Height of the Pyramid
a = Apothem Length of Pyramid
