32mm Iron Density Cube with Hook

This solid iron (Fe) density cube measures 32mm (1.2 inches) on each side and weighs 252g (approximately 9oz). An integrated hook extends the total height to 1.9 inches, allowing the cube to be easily submerged in and lifted from water or attached to a spring scale for measurement activities. The cube is part of the Density Investigation series, designed to help students understand the relationships between mass, volume, and density, as well as explore specific heat and specific gravity concepts. It is suitable for physics and chemistry classrooms at all grade levels. These cubes are designed for educational use and are not fabricated using ultra-high-precision machining. Dimensional tolerances fall within the plus or minus 5% range of stated dimensions, though they are generally tighter. Due to the nature of raw metals, some oxidation or corrosion may occur from humidity and storage. Any surface oxidation can be removed by lightly scuffing the affected area.
