Abstract A cuboidal structure is formed from six face plates each being squares having two pairs of opposite sides, one side of each pair containing a central recess and the other side lacking edge material to leave a central projection, the projections being the same height as the depth of the recesses, and the projections and recesses being substantially the same length. Six identical face plates are provided with the corner of each face plate between adjacent sides containing recesses having a square notch therein with sides equal to the depth of the recesses. A cuboidal structure formed by six identical face plates of the same thickness as the depth of the recesses has eight corner notches. If a cuboidal structure is formed from six identical face plates that are thinner than the depth of the recesses, each edge of the cuboidal structure will have a projection and edges adjacent to a recess extend past faces of the cuboidal structure. A perfect cube structure will result if four face plates are formed without corner notches and two more face plates are formed without corner notches and with each of the two face plates having one additional square extension from a corner between adjacent sides containing a recess and a projection, all six face plates having the same thickness as the depth of a recess.
A cube structure comprising, in combination, six square face plates each having two pairs of opposite sides, one side of each pair containing a central recess and the other side having a central projection, said projection and said recess being substantially the same length, and the depth of said recesses being the same as the height of said projections, said face plates being the same thickness as the depth of said recesses and the height of said projections, and two of said square face plates each having a square extension forming a corner between two of said sides of each of said two face plates, one of said two sides containing a recess and the other having a projection, said sqUare extensions having sides equal to the depth of said recesses and the height of said projections, said face plates being assembled into a perfect cube structure having edges with each edge having a projection of one face plate fitted into the recess of another face plate.
