Geometric Objects:

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.
