Which of the follow functions would best model this situation above?


Cube root

Polynomial

Piecewise

Absolute Value

Answer 1

By definition, the volume of a cube is given by:
 V = L ^ 3
 Where,
 L: cube side
 Clearing L we have:
 L = V ^ (1/3)
 Rewriting we have:
 L = 3 ^ root (V)
 Answer:
 A function that would best model this situation above is:
 Cube root
