Question

using eulers formula find out the number of vertices of polyhedron having 10 faces and 20 edges

Answer 1

Answer:

12

Step-by-step explanation:

ACC. To Euler's formula

F+V=E+2

10+V=20+2

V=22-10

V=12

Thus there are 12 vertices

Answer 2

Euler's formula = Face + Vertice - Edge = 2
Vertice = 2- Face + Edge
Vertice = 2-10+20
Vertice= -8+20
Vertice = 12
