Question

. A polyhedron has 30 edges and 20 vertices. How many faces does this polyhedron has ?​

Answer 1

Answer:

12 faces

Step-by-step explanation:

According to Euler's Formula,

F + V - E = 2.

Given, Edges (E) = 30, Vertices (V) = 20.

=> F + 20 - 30 = 2

=> F - 10 = 2

=> F = 2 + 10

=> F = 12.

Answer 2

12 faces is the right answer
