The layout of the complete surface of an object is named as a development. Geometric solids are bounded with geometric surfaces. They may be classified as given as:
(a) Solids bounded via plane surfaces as like tetrahedron, prism, and cube, pyramid.
(b) Solids bounded via single curved surfaces as like cone and cylinder is like generated via a moving straight line.
(c) Solids bounded via double curved surfaces as like sphere or like surface of revolution generated via curved line.
