Question

In a solid ,if F=V=5 ,then the number of edges in this shape is (a)6(b)4(c)2(d)8​

Answer 1

as per the Euler's formula .

F+V =E+2

here F is number of faces,

V is number of vertices ,

E is number of edges .

in Ur problem ,

F = V =5

then E = ?

by using Euler's formula

F+V=E+2

5+5=E+2

10=E+2

10-2=E

8=E .

therefore number of edges ( E) =8

hope helps uhh
