Answer:
Euler's formula for polyhedron is:
- V - E + F = 2
- where V- vertex, E- edge, F- face
As per the above formula the relationship between the vertexes, edges and faces is same for any polyhedron.
Lets confirm, have a look at the picture
(a) Tetrahedron, count each element:
Verify
- 5 - 8 + 5 = 10 - 8 = 2 - correct
(b) Hexagonal prism, count each element:
Verify
- 12 - 18 + 8 = 20 - 18 = 2 - correct
