100%
Assume you have a drop of 2 cm³ falling down.

**A)** If the drop is a cube, what is its surface area? (Hint, volume of a cube = L³. Surface area of a cube = 6 * L², where L is the length of the cube, and the factor of 6 as a cube has 6 faces).

**B)** For the same drop, what is its surface area if it is a sphere? (Hint, volume of a sphere = 4/3 * pi * R³. Surface area of a sphere = 4 * pi * R².)

**C)** Find the surface area to volume ratios of both objects. Which object (sphere or cube) has a lower surface area to volume ratio? Which shape does the drop favor?
