Question

please give answer of this question​

Answer 1

Answer:

1. V=6,E=12

Eular formula = V + F - E = 2

find :- F

6+F-12=2

F-6=2

F=2+6

F=8

the polyhedron have 8 faces

2. F = 20, E = 30 , V = 12

find :- is this polyhedron possible

Eular formula = V + F - E = 2

12+20-30 = 2

32-30 = 2

2=2

its verify

therefore, this type of polyhedron is possible

Answer 2

Answer:

pl thank you for the first one and the other
