Answer:
MN = 7 cm
Step-by-step explanation:
Well the volume we can separate into pieces
first the ABCDEFGH (? you know this cuboid)
which has a volume of

if you ask where does the 4 come from
it comes from LP = KB = YC and JY + YC =JC
so

this is because JY = MX
the other volume is of BCNPKLXY (hope you understand which one)
and the volume is

and the last one is KYXLMJ (the top "triangle")
the volume is

so now add them up
and has to equal 444

and finally we know that MN = MX + XN = 3+4 = 7
so here is our answer MN = 7 cm
a couple of notes

3. the units don't matter due to the fact that everything is in cm
4. see the picture below to get a better idea of which prism I am talking of
5. tell me if you have questions :D
