Answer 1

Answer:

formula-VERTICES+FACES-EDGES=2

Answer 2

Answer:

Step-by-step explanation:

Formula :- F + V = E + 2

F = Faces

V = Vertices

E = Edges

A) 14 + V = 36 + 2

14 + V = 38

V = 38-14

V = 24

B)17 + 17 = E + 2

34 = E + 2

E = 34-2

E = 32

C)F + 40 = 60 + 2

F + 40 = 62

F = 62-40

F = 22

D)11 + 18 = E + 2

29 = E + 2

E = 29-2

E = 27
