Just as the surface area-to-volume ratio depends on size, so can other properties. To see how, suppose that your size suddenly doubled; that is, your height, width, and depth all doubled. (For example, if you were 5 feet tall before, you now are 10 feet tall.)
A) By what factor has your waist size increased?
B) How much more material will be required for your clothes? (Hint: Clothes cover the surface area of your body.)
C) By what factor has your weight increased? (Hint: Weight depends on the volume of your body.)
D) The pressure on your weight-bearing joints depends on how much weight is supported by the surface area of each joint. How has this pressure changed?
