Question

we have 10 faces and 16 vertex find the number of edges with euler formula

Answer 1

F+V =E+2
10+16=E+2
26=E+2
26-2=E
24=E
So
Edges are 24

Answer 2

Hola

Here is your answer

Euler formula -

V + F - E = 2

Or

V + F = E + 2

Here

V = 16

F = 10

E = ?


Answer -

16+10=E + 2

26 = E + 2

26-2 = E

24 = E


Answer -

Edges = 24
