In these lessons, we will learn
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:
Nets are helpful when we need to find the surface area of the solids.
Here are some examples of nets of solids: Prism, Pyramid, Cylinder and Cone. Scroll down the page for more examples and solutions.
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.
