the surface area and average depth of the Pacific Ocean are 1.8 x 10^8 km^2 and 3.0 x 10^3 m. calculate the volume of water in the ocean in liters.
the answer should come out to be 7.0 x 10^20. can someone explain it.

I don't think that is the correct answer. 1.8 x 10^8 km = 1.8x10^11 m. When you multiply area and depth to get volume you need to use consistent units. Thats why it is necessary to convert kilometers to meters. Multiplying area x depth = volume.
Answer is 5.4 x 10^14 (cubic meters)
Not really a chemistry problem

Convert the km to m and find the cubic volume in cubic meters of the ocean. That works out to around 5.4 x 10^17 m^3,
Then determine the number of liters in one cubic meter and multiple the number of liters in a cubic meter times the volume in cubic meters.
The answer is going to bearound the figure you suggested.

I will explain it but you will do it:you need to find volume of the ocean using conversion factors. you will go from cubic meters to liters:
1. convert area of ocean from square km to square meters.
2. calculate volume of ocean in cubic meters: depth(height) times area
3. convert cubic meters to liters
Use the conversion units in your book.
Have fun!

5.4x10^17 m^3 so 5.4 x 10^20 i am getting
i guess the area includes the crust and troughs
or u mean any density change of water in depth due to temperature
But good question.
