Euler Formula
for faces, vertices  and edges 
$$ F + V - E = 2$$

jkbo · Answer

thank u can you help me with the other problem too please

unklerhaukus · Answer

re arranging to find the vertices 
$$V=2-F+E$$
and substituting
$$V=2-25+37=\cdots$$

jkbo · Answer

were did you get 25 and 37 from?

unklerhaukus · Answer

Edges: 37 = E
Faces: 25 = F

jkbo · Answer

i still dont get it sorry

unklerhaukus · Answer

Faces+ Vertices −Edges = 2
