Pyramid vs. Prism: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 17, 2023
A pyramid is a 3D shape with a polygonal base and triangular faces meeting at a point, whereas a prism is a 3D shape with two identical polygonal bases connected by rectangular faces.

Key Differences

Pyramids have a base that can be any polygon, and their sides are triangles converging to a single point. This point is not in the same plane as the base. Prisms, in contrast, have two bases that are congruent, parallel polygons, and their sides are parallelograms or rectangles, depending on the angle of the side edges.

In a pyramid, the number of faces depends on the base's shape; for example, a square base results in four triangular faces, plus the base. In a prism, the number of faces is always two more than the number of sides on the base; for instance, a triangular prism has five faces in total.

The volume of a pyramid is calculated as one-third the base area times the height, where the height is perpendicular from the base to the apex. In contrast, the volume of a prism is the base area times the height, where the height is the perpendicular distance between the two bases.

Pyramids are often associated with ancient structures, especially in Egypt and Mesoamerica, symbolizing architectural and cultural significance. Prisms are commonly referenced in optics and physics, particularly for dispersing light into a spectrum or reflecting images.

In geometry education, pyramids are used to teach about vertex figures and Euler's formula. Prisms are used to teach about surface area, volume, and the properties of different polygons, as the type of the prism changes with the shape of the base.
