• 3D shapes/objects are those which do not lie completely in a

plane.

• 3D objects have different views from different positions.

• A solid is a polyhedron if it is made up of only polygonal faces, the

faces meet at edges which are line segments and the edges meet at

a point called vertex.

• Euler’s formula for any polyhedron is,

F + V – E = 2

Where F stands for number of faces, V for number of vertices and

E for number of edges.

• Types of polyhedrons:

(a) Convex polyhedron

A convex polyhedron is one in which all faces make it convex.
