Surface area, as you know, is a planar measurement, and is measured in square units. Volume, on the other hand, is a solid measurement and is measured in cubic units. Both measures are necessary to understand a solid figure. For angular figures, such as prisms and pyramids, the area and volume calculations are straightforward, utilizing your knowledge of triangles and quadrilaterals. When you introduce curvature, as in a sphere, the calculations are not as intuitive?you will likely need to memorize the formulas. Is the ratio of surface area to volume of a sphere a constant, or does it vary with radius? How would you figure it? Which would cool faster in outer space?a large planet or a small planet? Why
