Question

O Can a polyhedron bave 20 Faces, 30 Edges and 12. Vestices prove by Eulers formula​

Answer 1

Possibility of this bring a polyhedron can be proved by Euler's formula, i.e

F+V-E=2

F=10 V=15 E=20

=10+15-20

= 25-20

5/2

Euler;s formula can't be proved.

Hence, a polyhedron can not have 10 faces,20 edges and 15 vertices.
