1. United States of America (USA) contains about 3,100 counties. Suppose you have a table in a database that stores for each county, its name (up to 40 characters), its description (up to 50 characters), its state (a two-letter code), its population and its median income (both as 32-bit numbers). How much memory space would the whole database take in kilobytes? Here, it is assumed that a single character is in 8-bit ASCII format.
