You are Orville Wright in 1925. The Smithsonian is presenting another airplane as the first in flight. Enraged, you look for another prominent museum to display your Wright Flyer. The London Science Museum is interested. The director of the museum loves experiments involving the volume of cones and cylinders. You can have the Flyer displayed there...so long as you prove you understand volume of cones and cylinders by producing four word codes and one date code.

You were first in flight. Make sure the world knows it by producing the volume codes. Good luck!
