I knew Africa was large. I did not know that Antarctica is larger than Europe at 5.5 million square miles (Europe is 4.0 million square miles).

I did not like the picture showing various countries contained within Africa. Why is Alaska not considered part of the "US"?

Several times while driving North through mid-western States I've been startled to realize how much land is north of the US border in Canada. I knew Canada was larger than the US, but I didn't comprehend the scale of that country.

I looked at his packing... he is comparing countries to a continent. In physics, that is called mixing units and your professor marks the answer wrong, regardless of whether the number is "correct."

He is comparing land masses. If he wanted he could stick a city in there for good measure, it's all about comparing things people can images with other things... No mixing of units here.
