A former mayor of Buffalo, New York suggested that residents grab a pack of beer to get through a pending snow storm. The local news station ran with the idea and formalized the notion that a six-pack of beer is recommended for a storm that would drop 2 feet of snow. Based on this recommendation, how many beers would Mayor Jimmy Griffin have recommended for the 1967 storm that dropped 58cm of snow on Chicago? Round to the nearest full beer if necessary.
