ABSTRACT:
A set of building blocks is provided suitable as a toy, as a design for the construction of structures such as walls, and as a design for the packaging of food and other items. The set includes blocks which are removably connected together. In one embodiment, the block had a top and bottom plane, three end planes and three side planes. The top and bottom plane are parallel to each other. The three end planes are perpendicular to both the top and bottom planes. A first end plane is equal in length to positive integer multiples of the length of each of the second and third end planes. The second and third end planes are perpendicular to a first side plane. The second and third end planes each project from opposite ends of the first side plane. The second end plane is distanced at a point between the first and third end planes. The first side plane is distanced at a point between a second side plane and a third side plane. The second side plane is equal in length to positive integer multiples of the length of each of the first and third side planes. The second and third side planes are opposed upward convergent at 45.degree. angles from the bottom plane extending to the top plane. The length is measured along a line parallel to the side planes and the top and bottom planes. The length of the first side plane is equal to a positive whole number multiple of the height of the block.
