The space station, Lupus-1, is an enormous spacecraft made up of three identical cylindrical structures that house the living quarters for the crew.  The three cylindrical structures are linked together by a series of tunnels that hold them together and allow the crew to move between cylinders. Each cylindrical structure contains 12 bedrooms, 7 bathrooms, and several kitchens. If the entire space station has 72 rooms, how many kitchens are there on the entire space station?
assistant
How many rooms are in each individual cylindrical structure? ** If there are 3 identical cylindrical structures, with a combined total of 72 rooms, then each individual cylindrical structure contains 72/3=<<72/3=24>>24 rooms.
How many kitchens are in each individual cylindrical structure? ** In each 24-room cylindrical structure, there are 24-12-7=<<24-12-7=5>>5 kitchens.
How many kitchens are on the entire space station? ** Thus, the entire, three-cylinder space station contains a total of 3*5=<<3*5=15>>15 kitchens.
