Answer:
see explanation
Step-by-step explanation:
Using Euler's formula for Polyhedra, that is
F + V - E = 2
where F is faces, V is vertices and E is edges
1
Rearrange formula for E
F + V - E = 2 ( add E to both sides )
F + V = 2 + E ( subtract 2 from both sides )
E = F + V - 2
= 25 + 17 - 2 = 40
-------------------------------------------------
2
Rearrange formula for F
F + V - E = 2 ( add E to both sides )
F + V = 2 + E ( subtract V from both sides ) F = 2 + E - V, so
F = 2 + 34 - 11 = 25
-----------------------------------------------------
3
Rearrange formula for V
F + V - E = 2 ( add E and subtract F from both sides )
V = 2 + E - F
= 2 + 36 - 22 = 16
