Question

In polyhedron F = 5, E = 8 then v is a. 3 b. 5 c. 7 d. 9

Guys please ans to get 20 points​

Answer 1

Answer:as the formula F+ V = E + 2

F = E + 2 - V

= 15 + 2 - 10

=7

so F = 7

ur option is c)

Step-by-step explanation:

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

In polyhedron F = 5, E = 8 then V is

a. 3

b. 5

c. 7

d. 9

CONCEPT TO BE IMPLEMENTED

Euler’s formula for Polyhedron :

For polyhedron F + V = E + 2

Where F stands for number of faces , V stands for number of vertices , E stands for number of edges .

Write down number of faces , number of vertices , number of edges

EVALUATION

Here by the given

F = Number of faces = 5

E = Number of edges = 8

V = Number of vertices = ?

Using Euler’s formula we get

F + V = E + 2

⇒ 5 + V = 8 + 2

⇒ 5 + V = 10

⇒ V = 10 - 5

⇒ V = 5

FINAL ANSWER

Hence the correct option is b. 5
