How Not To Define Surface Area: an 1890 Example Due to H. A. Schwartz (posted 11/08/2004, in pdf format). I learned this example from T. W. Korner's book, "A Companion to Analysis", page 218. Schwartz produced a simple triangulation of a cylinder for which the sum of the areas of the triangles converges to any chosen number greater than the true surface area, or even converges to infinity.
