Note: Make sure to use complete sentences when completing the following assignment.

Bruce Willis, Matt Damon, and Dwayne Johnson are at odds with a corrupt philanthropist. This being the case, they find a long steel pipe in an elementary school hallway with a bomb inside. As the evil philanthropist is evil, if they tilt the pipe so that it is not parallel to the floor, the bomb will detonate, killing our heroes (and others). In order to get this pipe out of the building, it must be carried down a hallway 9 ft wide. At the end of the hall there is a right-angled turn into a narrower hallway 6 ft wide. Matt Damon realizes that this corner might be a problem and asks the following question: What is the length of the longest pipe that can be carried (without blowing up) around the corner? Your mission, if you choose to accept it, is to find the answer to Matt’s question.

(This is basically problem 54 on page 309.)
