# Pyramid

**Pyramid**

Pyramids are one of the most complicated surface area formulas that do not involve a circle. A few measurements are required before the surface area can be derived. First, the length of a side on the base, or “b,” must be known. Next, like with a cone, the distance from the tip of the pyramid to the base, or “s,” must also be known.

The formula used for this calculation once those values are know is:

**2 * b * s + b^2**=surface area of a pyramid.
