I have know idea what kind of formaula you want us to use. I know that you said that p=3 ....y=ax^3 but I dont really know what to plug in where?? Thanks.
Assuming you are asking about the sandpile:
y is the amount of stuff in the pile--e.g., teaspoons of salt.
x is the diameter of the sandpile.
Plug in the number of teaspoons for y, the diameter for x.
