Cubic volume of sand blowing and reclamation in the South China Sea

80 times 10 to the sixth power. Zengmu shoal in the South China Sea is located at the southernmost tip, covering an area of about 2.2 square kilometers. China has always wanted to fill it into an island, but this is not a simple matter. First, Zengmu shoal is located about 30 meters underwater. If you want to fill in, you need 80 cubic meters of earthwork multiplied by 10. If calculated at an average price of 20 yuan per cubic meter, domestic issues such as comprehensive loading and unloading costs, road consumption, and wind and wave efficiency should also be considered.
