Question

if numbre of faces are of polyherdorn are 18 and their number of vertices are 10 then find the number of edges ​

Answer 1

Answer:

Step-by-step explanation:Euler's Formula = f+v=2+e

F=18 V=10

18+10=28

E=28-2=26 edges =26

Answer 2

f+V=e-2

18+10=e-2

28=e-2

so the edges are 28+2=30
