Stupid Amplitude...HELP!

So I am working on some phys homework and I had a question about this problem:
If the Amplitude of a sound wave is quadrupled, by what factor will the intensity increase?

And I thuoght that the relationship between Intensity and amplitude was that Intensity is proportional to the Square of Amplitude...and i don't know for sure...Can you all help?

This looks very much like a question that was in the k-12 section
and I will give the same answer:

You CAN'T do this if you don't know the relationship between amplitude and intensity- I'll bet that's in your textbook: Look it up!

well the whole reason i came here was because i couldn't find a direct relationship in my book about it...I tried figuring different things out but its still not the right answer. So, that's why I am totally lost with this question.
