Find the volume and surface area of the sphere. 10. WebSurface 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 S=6*L*L, where L is the length of a side. Similarly, the volume of a cube is V =L*L*L. So for a cube, the ratio of surface area to volume is given by the ratio of these equations: S/V = 6 ...
