The United States covers approximately 3.8 million square miles, making it the third-largest country in the world. In comparison, Africa is significantly larger at about 11.7 million square miles, making it the second-largest continent. Australia, on the other hand, is much smaller than both, with an area of about 2.9 million square miles. Thus, Africa is nearly three times the size of the U.S., while Australia is about 76% of the size of the U.S.
