Dear Brittany, Thank you for writing to T2T. The student has the right idea, but the wrong geometry :) The steel pipes would actually be the number of edges, and the 25 connecting joints would be the vertices. What's missing is the number of faces (that would be the number of panels the builder would need.) Substitute 40 for the number of edges, and 25 for the number of vertices in Euler's formula, and solve for the number of faces, and that will be the answer re: how many panels are needed. Hope this helps, -Ralph, for the T2T service
