I recently answered this question about how the volume of a tetrahedron depends on the surface areas of the faces. I like the content of this question a lot, but unfortunately the original wording was terrible. I have cleaned it up a bit, but I'm curious how much editing is permissible.
For example, would it be out of line to simply replace the text of the question with the following?
Is there a formula for the volume of a tetrahedron as a function of the areas $S_1$, $S_2,$ $S_3$, $S_4$ of the four faces?
This would certainly be helpful for anyone who arrives at the question via a Google search, but it seems to lose some of the content of the original question.
