The length of a cold storage is double its breadth. Its height is `3\ m e t r e sdot` The area of its four walls (including doors) is `108\ m^2dot` Find its volume.

Explanation

Let breath`=b`
Length`=2b`
height`=3`
Area of `4` wall`=108m^3`
`2(l+b)h=108`
`18b=108`
`b=6m`
Therefore,` l=2b =12m`
Hence, volume of the cold storage `=lbh`
`=12xx6xx3`
`=216m^3`
