# Regular Square Pyramid Formula

A regular pyramid is called so because this type of pyramid has a square base. A regular square has 4 triangular faces, 1 square base, 5 vertices and 8 edges.

The two major formulas for regular square pyramid are:

$\large Volume=\frac{1}{3}\, b^{2}h$

$\large Surface\;Area=2\,b\,s+b^{2}$

### Solved example

Question: Find the volume of a regular square pyramid of base length 6 cm and length 8 cm?

Solution:

From the volume formula: $Volume=\frac{1}{3}\, b^{2}h$

$Volume=\frac{1}{3}\times 6^{2}\times 8$

$Volume = 760.32\; cm^{3}$
