Question

in a solid,if f=v=5,then the number of edges in this shape is_

​

Answer 1

Answer:

The correct answer is option 8

For any polyhedron, Euler' s formula ;

F+V−E=2

Where, F = Face and V = Vertices and E = Edges

Given, F=V=5

On putting the values of F and V in the about formulae,

5+5−E=2

⇒10−E=2

⇒E=8
