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.

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.

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

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