What is meant by the net of a solid?
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:
1. Make sure that the solid and the net have the same number of
faces and that the shapes of the faces of the solid match the
shapes of the corresponding faces in the net.
2. Visualize how the net is to be folded to form the solid and
make sure that all the sides fit together properly.
Nets are helpful when we need to find the surface area of the
Nets of Prisms, Pyramids, Cylinders and Cones
