Prism vs Pyramid — Comparison Table
| Basis | Prism | Pyramid |
|---|---|---|
| Bases | Two parallel, congruent polygonal bases | One polygonal base |
| Sides | Rectangular or parallelogram sides | Triangular sides |
| Apex | No apex, has parallel edges | Single apex where triangles meet |
| Vertices | More vertices due to two bases | Fewer vertices, one at apex |
| Examples | Cube, cuboid, triangular prism | Tetrahedron, square pyramid, cone |
Key Points
- A prism has two parallel bases connected by rectangular faces
- A pyramid has one base with triangular faces meeting at an apex
- Prisms have uniform cross-sections while pyramids taper to a point
- Both are important 3D shapes in geometry and architecture
Frequently Asked Questions
What is the difference between a prism and a pyramid?
A prism has two identical parallel bases joined by rectangular faces (e.g. a triangular prism). A pyramid has just one base, with triangular faces that meet at a single top point called the apex.
How many bases does a prism and a pyramid have?
A prism has two identical bases; a pyramid has only one base.
Give an everyday example of a prism and a pyramid.
Prism: a Toblerone chocolate box (triangular prism). Pyramid: the pyramids of Egypt (square pyramid).
