  1. Wait patiently for a helper to come along.
  2. Once someone helps you, say thank you and close the thread with:
+close
  1. Feel free to nominate the person for helper of the week in #helper-nominations
  2. Do not ping the mods, unless someone is breaking the rules.
  3. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

So, the shape you're looking at is a tetrahedron. If you can find the distance from the vertex to the center of an equilateral triangle, you can use that as 1 of the legs of a right triangle, the other leg being the height of the tetrahedron. You can also find the height of the equilateral triangle and use that as the hypoteneus of your right triangle. Then use Pythagoreans theorem to fing the height of the tetrahedron. Finally V=BH/3 and that will be your final answer.

No calc is even necessary, only trig and geometry

Wait hang on, I was about to gi to sleep and I realized I'm wrong. The hypoteneus of the right triangle is just the side length of the tetrahedron.
