River sand is 179; 30 yuan, how much is it converted into a ton? Conversion formula?

River sand is a kind of solid mainly composed of silica, which can be divided into fine sand, medium sand and coarse sand according to the specifications. Fine sand with the particle size of 0.25-0.35mm, medium sand with the particle size of 0.35-0.5mm, and coarse sand with the particle size of more than 0.5mm. There are certain gaps in the sand, and the density of silica is 2.65g/cm3
Therefore, the density of river sediment is generally lower than this value, which is about 2T / M and 179
