The volume of tetrahedron

  1. Feb 21, 2008 #1
    i strongly thought that if we know every side of the tetrahedron,we can confirm its volume.
    but i just puzzled about how to find out the expression.
    please help me!

    there is another question:

    how can we find the relationship between its height and side?
    i know the formular v=sh/3,but it seems too complicated to apply it.
