Mass must be conserved, but the mass of a cylindrical prism is the product of sectional area and length, so the sectional area will be thirded, and that will reduce the diameter (=2r) by the square root of 3 (~1.7). -- Dana Emery To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
