I really need to know the answer to this extra credit problem. Please help!

A quantity, W, is directly proportional to X and the square of Y and inversely proportional to the cube of Z. W=3 when X=4, Y=2 and Z=4. What is the value of W when X=8, Y=9 and Z=6? Give answer to 3 decimal places.

Thanks in advance. I do not know much about inverse proportions.
