For any polyhedron solid the sum of and two more than the number of

Sum of vertices and sides is two more than the no. of edges.

Step-by-step explanation:

The basic formula is:

F+V-E=2

Or

F+V=E+2

(NOTE: This applies only for polyhedrons...which means that it doesn't apply for cylinders and spheres and the kind)

For any polyhedron solid the sum of its faces and vertices is two more than the number of its edges.

Vertices--

The vertices are the corner points of the polyhedron.

Edges--

The edges of a polyhedron are the line joining the vertices of two polyhedron.

Faces--

The faces are the flat surfaces by which a polyhedron is formed.

Euler formula--

The Euler formula is used to relate the vertices, edges and faces of a polyhedron.

If V denote the number of vertices.

E denote the number of edges and F denote the total number of faces of polyhedron.

Then ,

V-E+F=2

i.e.

             V+F=E+2
