Answer 1

Answer:

no

because faces +vertices - edges = 2

and your values is not satisfied this equation

please mark me as brainliest and follow me

Answer 2

Step-by-step explanation:

Here faces = 10, edges = 20, vertices = 15

According to Euler's formula.

F + V - E = 2

=> 10 + 5 - 20 = 25 - 20

=> 5 =/ 2

A polyhendron do not have 10 faces, 20 edges, and 15 vertices.
