Answer 1

Answer:

1)F=8

2)V=6

3)E=16

4)E=30

Step-by-step explanation:

Eulers formula

Faces(F)+vertices(V)=Edges(E)+2

first column:

E=12,V=6

F+6=12+2

F=14-6

F=8

second column:

F=5,E=9

5+V=9+2

V=11-5

V=6

third column:

F=9,V=9

9+9=E+2

E=18-2

E=16

fourth column:

F=20,V=12

20+12=E+2

E=32-2

E=30
