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:

Square Pyramidb22bs + b2(⅓) b2h
Triangular Pyramid½ ab(½) ab + (3/2) bs(⅙) abh


  • 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.
