I dont know how to do this problem:
If amplitude of a sound wave is quadrupled, by what factor with the intensity increase? Im lost...what is the relationship between the two? can anyone help me? [8)]

You obviously CAN'T do this if you don't know the relation between amplitude and intensity. That should be in your text. Look for it.
