A tube of Listerine Tartar Control tooth paste contains 6.6 ounces. As people use the tooth paste, the amount remaining in any tube is random. Assume the amount of toothpaste left in the tube follows a uniform distribution. From this information, we can determine the following information about the amount remaining in a toothpaste tube without invading anyone's privacy.

What is the standard deviation of the amount remaining in the tube?
