What is the Difference Between Pyramid and Prism?

🆚 Go to Comparative Table 🆚

The main difference between a pyramid and a prism lies in their shape and the number of bases they have:

  • Pyramid: A pyramid is a three-dimensional solid shape with a polygonal base (usually a triangle or a square) and triangular sides that meet at a point called the apex. Pyramids can have different numbers of sides, such as a triangular pyramid, a square pyramid, or a pentagonal pyramid, depending on the shape of their base.
  • Prism: A prism is a three-dimensional solid shape with two parallel congruent bases (usually rectangles or squares) connected by flat sides. Prisms can also have different numbers of sides, such as a triangular prism, a square prism, or a pentagonal prism, depending on the shape of their base.

Both pyramids and prisms are important shapes in geometry and have many practical applications in engineering and other fields.

Comparative Table: Pyramid vs Prism

Here is a table comparing the differences between a pyramid and a prism:

Parameter Prism Pyramid
Shape A prism has two identical ends and all flat sides. A pyramid has a base, and all sides lead from the base to join at the top point.
Number of Bases Two congruent and parallel bases. One base, which can be a polygon.
Sides (Lateral Faces) The faces or sides are perpendicular to the base faces. The sides are triangular in shape and meet at a point on the top called an apex.
Apex Does not have an apex. Has an apex.

Both pyramids and prisms are important shapes in geometry and have many practical applications in engineering and other fields.
