The author of this article, while recently working through some problem sets on determining volumes by triple integrals in cylindrical and spherical coordinate systems, realized that, although the textbook he was using included many interesting problems involving spheres, cylinders and cones and the increasingly complex solids that arose from the intersections of two or more of these, it did not include the common torus. He has written this brief guide for teachers who need some assistance with this technique, which he describes as a "long and arduous journey".
