**drwls**, Saturday, June 11, 2011 at 3:40amThe volume in cubic meters is the product of the ocean area (in m^2) and the average depth (in meters).

For the ocean area, take 68.1% of 4*pi*R^2.

For the mass of the water, multiply the volume by 1000 kg/m^3. Actually you should use a higher density of 1027 kg/m^3, corresponding to ocean salt water, since that is what most of it is.

Calculating these numbers yourself will improve your learning experience

**ashley**, Sunday, June 12, 2011 at 3:32pmI multiplied 68.1 X 5.099043638x10^14=3.472448717x10^16 to get the ocean area.

Then to get the average depth i took 1.21mix1609m=1946.89.

Then i multiplied the ocean area and volume i got to equal 6.760475683x10^19.

To get the mass, I took that answer and multiplied it to 1000 kg/m^3. I got 6.760475683x10^22. If i put that in significant figures it woud just be 6.76 x 10^22 kg right? was my method correct?
