Question from Jhezelle, a student: What is the formula of finding the surface area of a triangular pyramid? |
A pyramid is a geometric solid with one base that is a polygon and all other faces are triangles with a common vertex. A triangular pyramid has a triangular base so the surface is composed of four triangles. The surface area of a triangular pyramid is hence the sum of the areas of the four triangles that form its surface.
