I don't know but you have bad grammer * * * * * It is a net.
A geometric net of a 3-dimensional object is a single two-dimensional figure that can be folded into the 3-d shape.

The net of a cube
A two-dimensional shape that can be folded into a three-dimensional figure is often called a net.
Two dimensional object is a plane figure where as three dimensional object is solid (space) figure.
A projection is a 2 dimensional representation of a solid figure. See related link.

A geometric net of a 3-dimensional object is a single two-dimensional figure that can be folded into the 3-d shape.
A net is a two dimensional pattern that can be cut out and folded to make a 3-dimensional [solid] shape. A 2-dimensional shape, such as a square, does not have a net!
a rectangle or square
Since a frustum is a portion of a solid, three-dimensional figure, and a rectangle is a plane, two-dimensional figure, there can be no such thing as the frustum of a rectangle.
A pattern that you can cut and fold to make a model of a solid shape.
Plane figure
A solid is a 3-D object in which you can see all of the faces, edges, and vertices. A two dimensional figure is on paper and you cannot hold it in your hands.
