The volume is 27 3x3x3. 2p362p32 which will give you 54p. Surface area to volume ratio can be found easily for several simple shapes like for example a cube or a sphere.
For a cube the equation for surface area is S6LL where L is the length of a side.
If the areas were in the ratio 35 the lengths would be in the ratio _3_5. For a cube the equation for surface area is S6LL where L is the length of a side. Then you divide the surface areavolume which here is simply 1. Surface area of cuboid 2bbhhl Volume l b h where l length bbreadth and h height.
