6x10^9 = 6,000,000,000
8.79x10^5L = 879,000L
6,000,000,000 * 879,000L= 5,274,000,000,000,000L
5,274,000,000,000,000 Quadrillion liters
Or
6x10^9x8.79x10^5L
(6x8.79)x(10^(9+5))L
52.74x10^14L
5.274x10^(14+1)L
5.274x10^15L
Whew......

I hope this is just a math problem and not an environmental science problem.
From a practical viewpoint, it doesnt matter how many liters per person there are on the earth if the liters are frozen at the bottom of a glacier in Greenland and the person is in the Sahel or in rural Australia.
All that matters is, how many liters are there in the person's canteen.

6 x 8.79 x 10^(9+5)
52.74 x 10^(9+5)
5.274 x 10^(9+5+1)
5.274 x 10^15 L
