Question

If no. of edges is 25 and no. of faces is 15 find no. of vertices​

Answer 1

Answer:

From Euler formula,

F + V = E + 2

15+V=25+2

V=27-15=12

Answer 2

Question:-

➵ If number of edges is 25 and number of faces is 15 find number of vertices

Answer:-

Given :-

• Edges = 25
• Faces = 15

Aim :-

• To find the number of vertices.

By using Euler's formula :

F + V = E + 2

F,V and E representing Faces, vertices and edges respectively,

subsisting the values,

15 + V = 25 + 2

V = 27 - 15

V = 12

Hence number of vertices is 12.

Hope it helps!

Have a great day!!
