The weight of a square marble can be converted from its density (hardness) to its thickness, and the cubic marble can also be converted from its density (hardness). The domestic mainstream marble density (hardness) table is as follows; it can be seen from the chart that the domestic marble density is not much different, basically between 2.6g/cm3 and 2.9g/cm3. Through the formula; weight = marble volume × marble density. The thickness of conventional marble is 15mm 18mm 20mm 25mm 30mm. For example, the weight of a square of 18mm thick Foshan white marble is its volume 18mm3×2.7g/cm3=48.6kg. The final answer is the weight of a square of Foshan white marble. 48.6 kg.
Different thicknesses have different weights; thickness 15mm3×density 2.7g/cm3=40.5KG thickness 20mm3×density 2.7g/cm3=54KG thickness 25mm3×density 2.7g/cm3=67.5KG thickness 30mm3×density 2.7g/cm3=81KG The weight of a truck is 32 tons. The weight of the truck itself is more than 1.5 tons, and there are 30.5 tons 30500÷48.6 (18mm thick) = 627 square meters. Generally, Foshan white marble can carry about 610 square meters. Since the density of Foshan white marble is 2.7g/cm3, the weight of one cubic marble is 1m3×2.7g/cm3=2.7 tons.
