The pictured tetrahedron has four identical rectangular (i.e., right-angled or pythagorean) triangles as faces, with
What's its volume, as a function of p, q and r?
I like Geometry a lot, but I'd never heard about such a tetrahedron! I
already have half an answer: 1/6 times p times q times the height --
all I need now is the hegith and I'm done! ;-)
