How we convert 100 kg of 20 mm aggregate in to cubic meter?

To convert 100 kg of 20 mm aggregate to cubic meters, you need to know the density of the aggregate. The density of aggregate can vary, but a commonly used value is around 1.5 tonnes per cubic meter. So, you would divide the weight (100 kg) by the density (1.5 tonnes/m³ = 1500 kg/m³) to get the volume in cubic meters. In this case, 100 kg / 1500 kg/m³ = 0.067 cubic meters.
