A coustomer wants to make a teepee in his back yead for his kids. He plans on using PVC plumbing pipe for the supports on the teepee, and he wants the teepee to be 12 feet across and 8 feet tall. Howlong should the PVC plumbing pipe be?

How many upright supports does he want to use? Is he using any PVC pipe for the base?
