proportional relationships in a function  TOPIC_SOLVED

How do you determine if there is a proportional relationship in a function table? Is there some way to determine the rule by just evaluating the table of x and y values?

Sorry, I copied question and pasted. There is a box with a hint. It states that SA= 6 x e2 and V= e3, sorry I can't convert to exponents on this computer. So, given the V= 512 cc, how do I determine the minimum amount of paper needed to cover the box?
