Final answer:
The mass of the contents of the shipping container is 150 pounds.
Step-by-step explanation:
To find the mass of the contents of the shipping container, we first need to calculate the volume of the container. The volume of a right rectangular prism is given by the formula: volume = length * width * height. So, in this case, the volume of the container is 12.5 feet * 6 feet * 10 feet = 750 cubic feet.
Next, we need to calculate the mass of the contents by multiplying the volume by the average weight per cubic foot. The mass = volume * weight per cubic foot. Therefore, the mass = 750 cubic feet * 0.20 pound per cubic foot = 150 pounds.
So, the mass of the contents of the container is 150 pounds.
