each student requires 9m² of floor  

and given the no. of students is 50

So the total area of the room is 9m²X50=450m²

Given the length of the room is 25m

so the Breadth is =450/25=18m

each student requires 108m³ of space  

so total volume of the room is 108X50=5400m³

we know that : Volume=Area X h

                     so⇒5400=450Xh

                         ⇒h=5400/450=  12m
