How big is Russia? How many different lanuages are in Russia? What is Russian Population, or how many people are currently living there??

The total area of Russia is 17,075,200 sq km or 1.8 times the size of the United States. The population as of July 2004 was estimated at 143,782,338. THe main language spoken is Russian although there are others.

I found all this information on a CIA web site, maybe it could help you, address is http://www.cia.gov/cia/publications/factbook/geos/rs.html

Another site you might want to try is http://www.geographia.com/russia which tells you all about the country.
Hope this site is of some use for you. :)
