This solid aluminum density cube measures 20mm (0.78") on each side and includes a hook for easy lifting from water or massing with a spring scale. Including the hook, the cube is 1.5" in height. The cube is stamped with the element symbol (Al) for easy identification. Designed for educational use in density investigation, specific heat, and specific gravity experiments across all grade levels. Tolerances are in the +/- 5% range. Some oxidation may occur due to the nature of raw metals and can be removed by scuffing.
