Hi sogmat,

Please use the spoiler to hide the OA.

The resolution:
The Sides are in the ration on L:W:H = 3:2:2
So, the 3 sides can be assumed to be 3y, 2y, 2y

Volume of the cube
=> 3y*2y*2y = x
=> 12y^3 = x
=> y = CubeRoot(x/12)

Height
=> 2y
=> 2 * CubeRoot(x/12)
=> CubeRoot (8x/12)
=> CubeRoot(2x/3)

So, B is the correct answer
