Quizplus · Accepted Answer

When a cell expands in diameter, its volume increases by the cube of the diameter (d^3) because volume is proportional to the cube of length.

However, the surface area increases by the square of the diameter (d^2) since it is proportional to the square of length. Therefore, the best choice is C.
