## Number of Edges on a Rectangular Prism

**How many edges does a rectangular prism have?**

**12.**

A rectangular prism has 12 edges. It has the same number of edges, planes, and vertices as a cube. A rectangular prism fits into the rough definition of a cuboid, with each pair of adjacent planes meeting in a right angle. If the edges of a rectangular prism were made equal then it will become a cube.
