### What is Meant by Pyramid?

In mathematics, a pyramid is a polyhedron having a base and at least three triangular faces which meet each other at a single point called the apex. Based on the base, a pyramid can be a triangular pyramid, square pyramid, pentagonal pyramid, etc. the formula to calculate the base area, surface area and the volume of the square pyramid and the triangular pyramid are as follows:

Pyramid | Base Area | Surface Area | Volume |

Square Pyramid | b^{2} | 2bs + b^{2} | (⅓) b^{2}h |

Triangular Pyramid | ½ ab | (½) ab + (3/2) bs | (⅙) abh |

Here,

- b: base length of the triangular pyramid.
- h: height of the triangular pyramid.
- s: slant height of the triangular pyramid.
- a: apothem length of the triangular pyramid.
