### Theory:

A net may be a two-dimensional plan or shape which will be folded to form a three dimensional solid.
Example:
Here come the nets for the $$3D$$ shape cube.

Steps involved to make a $$3D$$ shape:
• Cutting out the net below.
• Fold along the dotted lines and use the tabs to glue the solid together.

Important!
Some of the nets like a square pyramid, rectangular prism, triangular prism, triangular pyramid, cylinder, and hexagonal prism are shown below.
