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.)
