What is meant by the Net of a Solid?

Nets

A net is a sort of skeleton – outline in 2-D, which, when folded results in a 3-D shape.
OR
A net of a 3-D figure is the shape that can be cut out of a flat piece of paper or cardboard and folded to make the 3D-shape.
OR
A solid figure may be changed into a plane figure by cutting some of the edges of the original figure and opening it out flat as a fold-out. Such a plane figure is called a net of the solid.
