Quizplus · Accepted Answer

Surface area : volume ratio is inversely proportional to the size of the cube. As the size of the cube decreases, the surface area increases more than the volume does, resulting in a higher surface area : volume ratio. Figure C has the smallest sized cubes, so it has the greatest surface area : volume ratio.
