Nets and Cross Sections

Here is a demo for intersections of a polyhedron and a plane:

Our entire world is three-dimensional – but it is often much easier to draw or visualise flat, two-dimensional objects. And there are a few different ways to view three-dimensional polyhedra in a two-dimensional way.

Describe the cross section formed by the intersection of the plane and the solid.

A cross-section is the intersection of a plane with a solid. Another way to represent a three-dimensional figure in a two dimensional plane is to use a net. A net is an unfolded, flat representation of the sides of a three-dimensional shape.
