Nets of a Solids

We will learn how to use nets to find the surface area of a solid?

Let us take a box made of cardboard. If we cut open the box and flatten it out, the flat shape is called the net of the box. A net is a two-dimensional shape that can be folded to make a three-dimensional shape. The net of a solid is a diagram drawn on a paper which when cut and folded along the lines can be used to construct a solid shape.

For example, the following diagram shows nets of a cube.

Nets of a Cube

Not every arrangement of six squares on a paper produces a net for a cube. For example, a row of six squares does not fold to form a cube.

Net for a Cube

The net of a cylinder without top and bottom would look like a rectangle.

Net of a Cylinder without Top and Bottom

Drawing a 3 – dimensional shape depends on its view from different positions. A solid shape viewed from the front will look different when we look at it from the top or from side. For example, a cylinder viewed from the front and side will look like a rectangle but when we look at it from top it is a circle.

Views of 3-D Shapes

The views of a solid from three different directions namely top, front and side are known as plan, front elevation and side elevation respectively.


The net of a cone would look like as given below.
