What is the difference between a triangular prism and a triangular pyramid?

Back

A triangular prism has two triangular bases, while a triangular pyramid has one triangular base and three triangular faces.

Front

What is the volume of a rectangular prism?

Back

The volume of a rectangular prism is calculated by multiplying its length, width, and height (V = l × w × h).
