Nets of simple solids

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.  

How to work out a net

 

Step 1, Find the base

Identify the base

 

 

 

 

 

Step 2, Unfold the 4 sides

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

Step 3, place the top

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.
