Expanding on the regular Geometric Solids set, these figures introduce a new shape - the hexagon - and demonstrate how a solid shape can be divided into smaller, familiar shapes. For example, the rectangular prism can be divided into three triangular prisms. The set includes five pieces: a solid hexagonal prism; a divided hexagonal prism, a solid rectangular prism; a divided rectangular prism; and a solid cube. The prisms measure 12 cm tall (about 5") and are made of solid, lightweight basswood with a blue finish. This set does not include a storage box.
