a customer wants to make a teepee in his backyard for his children. he plans to use lengths of PVC plumbing pipe for the supports on the teepee, and he wants the teepee to be 12 feet across and 8 feet tall. How long should the PVC plumbing pipe be?

appears to be a regular rightangled triangle problem, where the PVC pipe is the hypotenuse.
so H^2 = 6^2 + 8^2
H^2 = 100
H = 10
Each of the support pipes should be 10 feet long, ignoring any extra length needed for fastening.
