Guide
1
first determine the density of the sand.Contact mass and volume of the material is expressed by the indicator.Each material has its own density, and it is constant.This characteristic is measured in kilograms per cubic meter.Identify it can be using a physical directory containing the appropriate table.Natural sand density is 1300 kg / m3.Worth noting that, together with humidity increase the density of the sand will also increase.To calculate the following values: the density of the wet sand of 1500 kg / m3, the density of the wet sand with clay impurities 1800 kg / m3.
2
calculate the mass of sand.Th
e formula that relates the volume and weight is as follows:
m = V ∙ r,
where m - mass;V - volume;p - the density.
As seen from the above relations, in order to find the mass of matter, knowing the scope thereof, it is necessary to multiply the value of this volume by the density of matter.Moreover, the value of V is a known amount of cubes.

Move the weight value obtained from kilograms to tonnes.Tabular density has the dimension kg / m3.Accordingly, the value obtained in the calculation would show a lot of sand in kilograms.To translate this value into tons, need to know that 1 ton is 1000 kg.Thus, resulting in the number of calculations to be divided by 1000. The result - mass of sand available, expressed in tonnes.

Consider an example.Suppose there are 12 cubes of moist sand.Determine its mass.
1. Density of moist sand p = 1500 kg / m3.
2. The amount of sand V = 12 m3.Its mass m = 12 * 1500 = 18000 kg.
3. 18,000 kg = 18000/1000 = 18 tons.
