Question: The breadth of a room is twice its height and is half of its length. The volume of room is 512 dm2. Its dimensions are:
Solution:
Let b be the breadth of the room
Height will be b/2 and length will be 2b.
Volume of room = Volume of a cuboid
We know that, Volume of a cuboid = l x b x h
Volume of room = 2b x b x b/2
512 dm2 = b3
b = 8 dm
Therefore, l = 16 dm and height = 4 dm.
Hence, the dimensions of the room are 16 dm, 8 dm, 4 dm.
