The Indian Ocean contains approximately 20% of the water in the World Ocean What is the approximate volume, in cubic kilometers, of water in the World Ocean? Write your answer in scientific notation. _____ cubic kilometers The Southern Ocean, the fifth ocean, contains the rest of the water in the World Ocean. What is the approximate volume of water, in cubic kilometers, contained in the Southern Ocean? Write your answer in scientific notation. Show your work. _____ cubic kilometers

Explanation / Answer

PartA:let the vol of world ocean be x..

Then indian = 20%of world ocean..

Hence vol of world ocean=(100/20)*2.64*10^8

=5*2.64*10^8=13.2*10^8cubickms

PartB: southern ocean vol=world ocean vol- remaining 4 oceans vol..

=(13.2-(3.1+2.64+6.6+0.188))*10^8

=(13.2-12.528 )*10^8

=0.672*10^8

=6.72*10^7 cubic kms
