Question

2. A three dimensional shapes with 20 faces and 10 vertices. Find the number of edges of the
shape using Euler formula​

Answer 1

Answer:

If we now look at the icosahedron, we find that V = 12, E = 30 and F = 20. Now, V - E + F = 12 - 30 + 20 = 32 - 30 = 2, as we expected. Euler's formula is true for the cube and the icosahedron.

Answer 2

Answer:

The number of edges of the

shape or 80
