Size of Texas?

Afghanistan is located in Central Asia and specifically upon the geologic Iranian plateau, and is 647,500km² (similar to the Australian state of New South Wales, or the Canadian province of Manitoba, and slightly smaller than the U.S. state of Texas). The country is landlocked and mountainous, containing most of the Hindu Kush. There are four major rivers in the country: Amu Darya, Hari Rud, and the Kabul and Helmand Rivers.
