AIME 2001b Problem 15

  • Paper
  • Answer

Let EFGHEFGH, EFDCEFDC, and EHBCEHBC be three adjacent square faces of a cube, for which EC=8EC = 8, and let AA be the eighth vertex of the cube. Let II, JJ, and KK be the points on EF‾\overline{EF}, EH‾\overline{EH}, and EC‾\overline{EC}, respectively, so that EI=EJ=EK=2EI = EJ = EK = 2. A solid SS is obtained by drilling a tunnel through the cube. The sides of the tunnel are planes parallel to AE‾\overline{AE}, and containing the edges, IJ‾\overline{IJ}, JK‾\overline{JK}, and KI‾\overline{KI}. The surface area of SS, including the walls of the tunnel, is m+npm + n\sqrt {p}, where mm, nn, and pp are positive integers and pp is not divisible by the square of any prime. Find m+n+pm + n + p.
