In these lessons, we will learn:

### What is meant by the net of a solid?

A **geometry net**
is a 2-dimensional shape that can be folded to form a
3-dimensional shape or a solid. Or a net is a pattern made when
the surface of a three-dimensional figure is laid out flat showing
each face of the figure. A solid may have different nets.
### What is the net of a Cube?

**How many nets are there for a cube?**

**What is the net of a Cuboid?**

**How to draw a net of a rectangular prism or cuboid?**
**How to create different nets of a cube and rectangular prism?**

### Nets of Prisms, Pyramids, Cylinders and Cones

**Nets of a cuboid, triangular prism, cylinder, and square pyramid.**

Learn about faces, edges and vertices.

**How to identify the 3-dimensional shapes made by the nets - cube,
rectangular prism or cuboid, triangular prism, and pyramid?**
**Analyze the net of a cylinder to determine volume and surface area**

The diagram below shows a net for a cylinder.

a. Suppose the net is assembled. Find the volume of the cylinder.

b. Find the surface area of the cylinder.

**How to use nets and 3-dimensional figures to find surface area of cubes and prisms?**
**Interactive animations for nets of solids**

- What is meant by the net of a solid?
- Nets of the following solids: cube, rectangular prism or cuboid, triangular prisms, pyramids, cylinders and cones.
- How to use nets to find surface area?

Below are the steps to determine whether a net forms a solid:

1. Make sure that the solid and the net have the same number of faces and that the shapes of the faces of the solid match the shapes of the corresponding faces in the net.

2. Visualize how the net is to be folded to form the solid and make sure that all the sides fit together properly.

Nets are helpful when we need to find the surface area of the
solids. Scroll down the page to see how the nets fold to form the various shapes.

A cube is a three-dimensional figure with six equal square faces.

There are altogether 11 possible nets for a cube as shown in the following figures.

A rectangular prism or cuboid is formed by folding a net as shown:

Here are some examples of nets of solids: Prism, Pyramid, Cylinder and Cone

Learn about faces, edges and vertices.

The diagram below shows a net for a cylinder.

a. Suppose the net is assembled. Find the volume of the cylinder.

b. Find the surface area of the cylinder.
