A perscription, schedule III, narcotic analgestic (pain killer) containing hydrocodone and acetaminophen (Tylenol). Hydrocodone is actually an opiate, like heroin, that gives an amazing euphoric body high but it's also very addictive (although not nearly as addictive as heroin).
Unlike basketball and football, there is no way of knowing how long a game of volleyball will be. Like the others have already said, whoever wins the first 3 out of 5 sets wins the game. How long that can take can be anywhere from 30 minutes to 2 hours. (I've played in both).
The short court dimensions are 8 meters by 8 meters for each side of the volleyball court or 16 meters by 8 meters for the entire volleyball court. The standard dimensions for a volleyball court are 30 feet by 30 feet for each side or 60 feet by 30 feet. A meter is about 39 inches long, so this reduces the size of each side of the volleyball court from 30 feet by 30 feet to about 26 feet by 26 feet.
