Density Cube Set, 6 Metals, 20mm

This density cubes set includes 6 solid metal cubes: brass, lead, iron, copper, aluminum, and zinc. Each cube measures 20mm (0.8 inches) on each side and features a stamped element symbol for easy identification. A plastic snap-top case is included for storage. The set supports a wide range of physics and chemistry activities including density investigation, specific heat measurement, and specific gravity exploration. Due to the nature of raw metals, minor oxidation may occur and can be removed by scuffing. Designed for educational use with tolerances in the ±5% range.
