Abstract
Abstract A puzzle consisting of eight component pieces which fit together to fill out the volume of a cube four units wide by four units long by four units high, and also fill out the volume of a square eight units wide by eight units long by one unit high. A unit may be any length measurement unit, such as a centimeter. The volumes of the cube and the square are subdivided into sixty-four unit cubes, each unit cube having dimensions one unit by one unit by one unit. Each of the eight component pieces consists of eight unit cubes joined firmly together with their side surfaces flush one against the other, to form a connected two-dimensional shape of unit thickness. In six of the ten embodiments disclosed herein, all of the surfaces of pieces that comprise the top surface of the square assemblage become interior surfaces in the cube assemblage, thereby allowing for separate pictures to appear on the top surface of the square assemblage and the outside surfaces of the cube assemblage.
