please answer me fast and do not spam :(

Answer 1

Answer:

1. Faces + Vertics - Edges = 2

Faces + 6 -12= 2

Faces = 2+6 = 8

2. 20+12-30= 2

32-30= 2

2= 2

L.H.S = R.H.S

hope it will help you dear ☺️

Answer 2

Step-by-step explanation:

Euler's polyhedron formula, V−E+F=2

V = number of vertices = ?

E = number of edges = 12

F= number of faces = 6

V−12+6=2

V=6+2

V=8

Number of vertices = 8
