MHB How to Use the General Slicing Method to Find the Volume of a Tetrahedron?

[alane1994]

This is a homework problem, but, my professor is OK with me getting help as long as I don't solely get answers without guidance.
I am unsure how to start this, I don't really understand it I suppose...
Anyway, here is the problem.

Use the general slicing method to find the volume of the tetrahedron (pyramid with four triangular faces), all of whos edges have length of 3.

Any help would be appreciated!:)
