14-Piece Volume Set


These transparent, durable plastic shapes may be filled with colored water, rice, or sand to illustrate volume relationships by pouring from one to another. Set consists of all the consistently-used “regular” shapes and serves to familiarize students with the descriptive terminology. All are clear plastic, and the square pyramid, short cylinder, cube, cone, and hemisphere have colored bases. The sphere is 10 cm dia.; the cone, hemisphere, and short cylinder are each 12 cm dia. and have altitudes equal to their base radii. The cube and square pyramid are each 10 cm high; the other eight are all 15 cm high, and matching pairs have congruent bases.
