# Can a polyhedron have 10 faces, 20 edges and 15 vertices?

**Solution:**

According to Euler’s formula in any polyhedron, F + V - E = 2, where ‘F’ stands for a number of faces, ‘V’ stands for a number of vertices and ‘E’ stands for a number of edges.

Given that,

Number of faces, F = 10

Number of edges, E = 20

Number of vertices, V =15

Let’s verify Euler’s formula,

F + V - E = 10 + 15 - 20

= 25 - 20

= 5 ≠ 2

As we know that according to Euler’s formula in any polyhedron, F + V - E = 2. The above condition doesn't satisfy Euler's formula. Thus, we cannot have a polyhedron with 10 faces, 20 edges and 15 vertices.
