# Geometry - Nets Of Solids

In these lessons, we will learn

• 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?

### 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.

Here are some 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.

### Nets Of Prisms, Pyramids, Cylinders And Cones

Here are some examples of nets of solids: Prism, Pyramid, Cylinder and Cone. Scroll down the page for more examples and solutions. ### What Is The Net Of A Cube?

A cube is a three-dimensional figure with six equal square faces. How many nets are there for a cube?

There are altogether 11 possible nets for a cube as shown in the following figures. What is the net of a rectangular prism or cuboid?

A rectangular prism or cuboid is formed by folding a net as shown: How to draw a net of a rectangular prism or cuboid?

How to create different nets of a cube and rectangular prism?

Nets of a cuboid, triangular prism, cylinder, and square pyramid.
Learn about faces, edges and vertices.

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.
