Answer 1

Answer:

hi dear

euler Formula is

F+V=E+2

where F is the number of faces, V the number of vertices, and E the number of edges.

Step-by-step explanation:

1) 8+a=12+2

8+a=14

a=14-8

a=6

so for the first answer is 6 vertices

2) 20+12=2+b

32=2+b

32-2=b

30=b

so for the second answer 30 Edges

this is your answer
