How would you find the capacity a freight car?

The capacity of a freight car is typically measured in cubic meters or cubic feet, and can be determined by multiplying the length, width, and height of the car's interior. For example, a freight car with dimensions of 12 meters (length) x 2.5 meters (width) x 3 meters (height) would have a capacity of approximately 90 cubic meters. In imperial units, this would be equivalent to 3,200 cubic feet. Some freight cars may have varying dimensions and capacities, so it is important to refer to the specific specifications for each car to determine its exact capacity.
