The dimensions of a cuboid are in the ratio of `1:2: 3.` So, let the dimensions be `x , 2x , 3x` in metres. its total surface area is 88 cm^2. find the dimensions.

Explanation

total surface area of a cuboid`=2(lb+bh+hl)`

`88cm^2=2(2x^2+6x^2+3x^2)`

so `88=11x^2`

`x=2(2)^(1/2)`

so dimensions are `2(2)^(1/2),4(2)^(1/2),6(2)^(1/2)`
