The density of sand can vary based on various factors such as the type of sand, the particle size distribution, and the moisture content. However, on average, the density of sand is around 2,600 kg/m³ (160 lb/ft³). This means that for a volume of 1 cubic meter, the mass of sand would be 2,600 kilograms.
