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

Explanation

`Area = 108m^2`
`Height = 3m`
Length of a cold storage is double its breadth
So, Let breadth of a cold storage =` x `
length of the cold storage = `2x` Area of four walls
` 108m^2`
`2(l + b)xx h = 108 `
` 2 (x + 2x)xx3 = 108 `
` 6(3x) = 108`
` x = 108/18`
` x = 6`
Breadth of a cold storage = `6m`
Length of a cold storage =` 2xx6`
`12m`
Hence, Volume of the cold storage =` l xx b xx h`
`12 xx 6 xx 3 `
`216m^3`
