100,000 square miles because 10^5 is 100,000
2 :
4.65*10^5=465000 (total people) 465000/470=989.36 which rounds down to 989 square miles
3 :
(469000)/(470) = 998 square miles. -John

4.69x10^5 is scientific notation, so you just move the decimal point over five places. The population is 469000. So just divide by the population density and you will get the number of square miles. 469000/470=997.872 Rounded to the nearest square mile is 998. ----------------------------------------------------------------- To Rudy B, it is 4.69x10^5, not 4.65

You take the population and divide it by the density 4.69 * 10^5 = 469000 469000/470 = 997.87 or 998 square miles
