Density refers to the ratio of an object's mass to its volume. Therefore, the density of an aluminum sphere depends on both its mass and volume. According to the International System of Units (SI), the density of an aluminum sphere is measured in kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³). In practice, the density of an aluminum sphere is independent of factors like size and shape, and is generally around 2.7 g/cm³.
