Question

the breadth of a room is twice its height and half its length and the volume of the room is 512 cm find its dimensions

Answer 1

 we have,

        b=2h and b = l/2 = l/2 = 2h = 4h = l =4h, b= 2h

   Now,

          volume = 512 dm cu = 4h 2h  h

                            512 = 8h cu

                           512/8 =h cu

                             64= h cu

                             h = 4dm.

   So,

       l = 16dm, b = 8dm, h = 4dm.

i hope is a right answer...
