Towers A, B, and C house mostly first-year freshmen. The towers are all of different heights, and differ slightly in their living accommodations. Tower B is the tallest of the three, at 22 stories. Tower A is 19 stories tall, and Tower C is 16 stories in height. Rooms in Towers A and B are the same size, roughly 17 ft (5.2 m) by 11 ft (3.4 m). These measurements are not exact, however, because the three towers are cylindrical in shape (although actually twenty-sided) and the rooms themselves are therefore somewhat trapezoidal.
