Cube Dissection, Three-Piece Puzzle The cube can be dissected in countless ways for puzzles, and here's a Reid dissection that results in three congruent pieces. It takes exactly three copies to make a complete cube, making it surprisingly simple to assemble. To grasp the idea behind this Reid dissection, consider a 2 x 2 x 2 cube, which consists of 8 unit cubes. Each unit cube can be dissected into six congruent square-based pyramids. A 2^3 cube therefore has an astonishing 48 pyramids, which can be divided into three distinct groups, each forming a puzzle piece. Have fun exploring the fascinating connection between math and art!
