To provide you with the correct volume of the shopping mall, I would need specific dimensions or details about the mall's structure. The options you've listed (603 m³, 3,825 m³, 1,800 m³, and 3,015 m³) represent potential volumes, but without additional context or information, such as the floor area and height of the mall, it's impossible to determine which of these values is accurate.
If you have the dimensions (length, width, and height), please provide them, and I can help you calculate the volume.
