Consider two enclosed cylindrical tanks filled with air. Tank A is 8 ft tall while tank B is 7 ft tall, their diameter is both 6 ft. If the pressure and temperature inside both tanks are maintained equal, how much mass of air is inside tank B if tank A is filled with 3,872 Ibm of air? Solve using standard English units. Express your answer in slugs and round off to the nearest hundredths.
