50*9=450 =l*b=25b
so,breadth(b)=18 m
and
total volume=108*50=5400=lbh=25*18*h
so,h=12m
so,breadth(b)=18 m
and
total volume=108*50=5400=lbh=25*18*h
so,h=12m

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
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

each student requires 108m³ of space
