Other major urban centers were Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk (Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR) and Novosibirsk (Russian SFSR). It was the largest country in the world by surface area, spanning over 10,000 kilometers (6,200 mi) east to west across 11 time zones and over 7,200 kilometers (4,500 mi) north to south.
