The volume of the room =378m³
                       lxbxh=378........1 (where l,b,h are the length,breadth and height of room )
given ,area of the floor =84m²
                           lxb=84.....2
put the value of lxb from 2 in 1
lxbxh=378
84xh=378
     h=378/84
     h=4.5 m ans

As the volume of the room is 378 cubic meters.
so,l*b*h =378 cubic meters.
And the area is 84 meter square.
so, l*b = 84 meter square.
l*b*h=378
84*h= 378
h = 378/84
h = 4.5 meters
