Calculating Change in Volume at 8.80 km Deep

[starfish794]

Consider a point in the ocean about 8.80 km deep. The pressure at that point is huge, about 9.08 107 N/m2.
(a) Calculate the change in volume of 1.00 m3 of water carried from the surface to this point in the ocean.

I don't get why the answer isn't zero. But anyway, I found the density at that point to be 1052.88 kg/m^3. Should I be using pv=pv to find the change in volume?

Someone else is looking at this same problem but with a somewhat different depth number. What information did you use to get that density?
