Nets of Simple Solids

Lesson

A net is the shape that is formed by “unfolding” a three-dimensional figure. The net shows all the faces that make up the surface of the figure.

Nets are often used to construct 3D figures, and you may have had the chance to make some already. If not you can check out the investigation where you can make a variety of nets for different solids.

Identify the base

Unfold the four sides that are adjacent to the base

The two red end pieces,

the front and

the back.

the last step is to place the top piece

it could be attached to the front,

or either the edge pieces or the back

This applet is really cool as it shows you the whole process for creating and unfolding a net.

Based on the net, classify the following solid:

Triangular Prism

ASquare Pyramid

BSquare Prism

CTriangular Pyramid

DTriangular Prism

ASquare Pyramid

BSquare Prism

CTriangular Pyramid

D
