How to calculate the volume of prisms and cylinders

A prism is a 3D shape where its cross-section is the same along it’s length. In other words, if you cut a prism anywhere along its length, the shape formed is identical to the ends of the prism.

For example, a prism with a square cross-section is a cuboid, a circle cross-section gives a cylinder and a triangle prism gives a triangular prism!

 

The base multiplied by the length (l) gives the volume of a prism.

 

The base is either end of the prism, and is an area (units are in cm2!), when multipled by length it gives the volume 3 dimensions and is in cm3

 

For example, the volume of a cyclinder is V = (2πr) x length
