# Optimization problem

Here is the word problem:

A mass of clay of volume 432in^3 is formed into two cubes. What is the minimum possible total surface area of the two cubes? What is the maximum?

I have determined the following:

Surface Area (SA) = 6a^2

Volume of a cube (V) = a^3

I am not sure how to setup the formula to determine the asked for values to get to the derivative part of the problem. Any help would be greatly appreciated.
