Hi, Can someone help me to compute the volume of the tetrahedron by triple integral? (see figure attached). Tetrahedron1.jpg I need help please... Let's suppose, for example, we have integrand f(xi,eta,zeta)=1, and I want to compute the volume by triple integral, how should the limits be defined? I am trying to define the limits for the triple integral and then compute the volume in order to validate the result, but I see that the result is not correct. There is no mistake in the computation because I used in Wolfram Mathematica symbolic integration. In addition, I am looking for integral without dividing the tetrahedron to sum integrals. Can someone help me please? Thanks, Itay. Last edited by skipjack; July 6th, 2017 at 05:24 AM.
