need help with question 5 (a)

For question 5a) Please provide what are the images H,J,K and other are incomplete

5b) Using the euler formula

V - E + F = 2

F = E + 2 - V

F = 15 + 2 - 10 = 7

Hence the number of faces in the polyhedron is equal to 7

5c) Using the euler formula

V - E + F = 2

V = E + 2 - F

V = 30 + 2 - 10 = 12

Hence the number of faces in the polyhedron is equal to 12

5d)

Let the number of vertices be 2p+1

Let the number of edges be 2q + 1

Using the formula

V - E + F = 2

2p + 1 - 2q -1 + F = 2

F = 2 + 2q - 2p = 2(1+q-p)

Hence F will always be an even number

Hence it is not possible that all of three will be odd
