Imagine That You Are an Interior Architecture/biology Double Major

Essay

Imagine that you are an interior architecture/biology double major. While at home during break, one of your friends asks you to design and help build a spiral staircase that is modeled after a DNA molecule. The staircase must have 12 steps and each step needs to be 6 feet wide. You say, "OK, as long as you provide the materials." Then your friend shows you what you have to work with: a couple of spiral railings and some boards. The trouble is the only boards he has for you to work with are either 2 feet long or 4 feet long. Explain why you are still able to design and build the staircase using the materials he has on hand.
