# 3D Paper Nets

### Concept

It is possible to make three-dimensional objects, such as a pyramid or cuboids, from paper with only two dimensions. All you need to know is the “3D Net” corresponding to the solid.

### Types of solids

Understanding the names of various solids is essential - especially when you need to articulate what shape you’re looking for to someone else. “Square-base Pyramid? Got it!”…without having to make a bunch of air gestures to explain what kind of solid you need.

#### Cube

#### Cuboid

#### Prism

#### Triange-base Pyramid

#### Square-base Pyramid

#### Cone

#### Cylinder

Or at least, it’s trying to be. :)

### Solids and Nets

Each of the above solids can be created using their two-dimensional nets. For example, to create a *cube* here is one of the nets you can use.

Infact, there are eleven possible nets for a cube. In each of the cases, none of the faces will overlap which means they will create a perfect cuble.

Try to fold in your mind (that’s the fun part!) and see if any of the faces overlap. None should. But what about below?

### Activity

You can make paper nets at home, or buy pre-made ones (with flaps that make it convenient to build the solid) from amazon.
