This problem can be directly solved by ratio and proportion.

We know that there are 646,449 people for every 68.3 square miles, so:

646,449 people : 68.3 square miles = X : 570,374 square miles

We know that the : symbol signifies division therefore,

646,449 / 68.3 = X / 570,374

X = 5,398,502,224 people
