Question

The breadth of a room is twice its height, one half of its length and the volume of the room is 512cu. m. Find its dimensions.

Answer 1

We have,

`b= 2h  and  b =1/2`

`⇒1/2=2h`

`⇒l=4h`

`⇒l  = 4h, b= 2h`

Volume `= 512m^3`

`⇒ 4hxx2hxxh = 512 `

`⇒ h^3 = 64`

`So , l = 4 xx h= 16m`

`b= 2xxh=8m`

`and h=4m`
