When you're rounding the area of a country to 1 significant figure, it would result in a lot of countries being given the same area, not making it evident which country was bigger and which wasn't.

Canda's area in square kilometres (according to a certain website) is: 9976140

USA's area in square kilometres (according to a certain website) is : 9629091

China's area in square kilometres (according to a certain website) is: 9596960

If you rounded them all to 1 significant figure they would all be 'approximately' - I use that term loosely - 1 million square kilometres. If this was an atlas, and you were trying to find which country had the biggest area excluding Russia, this wouldn't be helpful at all.

Hi, that's an obvious answer but you have to think of one that refers to the units not big enough to determine its size!
