What is a geometric net?

•  net is the shape that is formed by unfolding a three-dimensional figure. In other words, a net is composed of all of the faces of the figure.

• Free from all charges or deductions: such asa : remaining after the deduction of all charges, outlay, or loss

• They are devices made from fibers woven in a grid-like structure, and are usually meshes formed by knotting a relatively thin thread.
