The cube consists of 3 small cubes and 24 prisms, that can be used to build a big cube. The picture on the cover as well as the rule that only the same coloured surfaces must touch helps with the control of error. A beautiful presentation and more information can be found in Linda's Montessori Shop or on YouTube.
