It depends on the figure.
There are simple formulae for cuboids (including cubes) and ellipsoids (including spheres). Those for other regular polyhedra and some other shapes are not too complicated, but there are also shapes where there is no option but to calculate the area of each face and sum the individual areas. And, if the shape is completely irregular, even that may not be an option.

How do you calculate the surface-area-to-volume-ratio?
The surface-area-to-volume ratio may be calculated as follows: -- Find the surface area of the shape. -- Find the volume of the shape. -- Divide the surface area by the volume. The quotient is the surface-area-to-volume ratio.
