A machine can pack a 3ft. by 2ft. by 1ft. carton with styrofoam “peanuts” in 7.5 seconds. How long would it take to fill a carton that measures 4ft by 6ft by 6ft? Possible answers: 180 sec, 45 sec, 20 sec, or 75 sec?
The answer is 180 seconds. The reason for this is that the second carton is 24 times the volume of the first one; so, the time taken to pack the container would be 24 times longer. This means that the answer would be found by the equation 7.5 * 24 which is evaluated to 180 seconds
