The more floors there are, the more area there is to rent and obtain income. However, more floors also means more weight and more dead loads. There is a maximum and minimum number of floor areas. Winning the competition often denotes the need for the maximum floors to get the most rentable income. Different factors such as construction or shipment costs may lead every team to making a different choice about the number of floors in their structure. (Section 8.2.d)
