A net is a two-dimensional representation of a three-dimensional figure that is unfolded along its edges so that each face of the figure is shown in two dimensions.

Consider the rectangular prism shown.

Consider how the net below will fold to create the prism.

The example shown above is a polyhedron.

In a previous lesson, you discovered Euler's Theorem for the relationship among vertices, faces, and edges of three-dimensional solids.

In that same lesson, you worked through conjectures about three-dimensional solids. Now, you will use the information that you learned from that lesson and begin working with the nets of three-dimensional solids.
