###Human: A fan can create an airflow of 10 liters per second. If the fan works for 10 minutes each day, calculate the amount of airflow it will create in one week., ### Assistant: If the fan works for 10 minutes each day, in a week with 7 days, it will have worked for 10*7 = 70 minutes.
Since a minute has 60 seconds, the total time in seconds that the fan will have worked in one week is 70*60 = 4200 seconds.
Since the fan can create an airflow of 10 liters per second, in 4200 seconds, it will create an airflow of 4200*10= 42000 liters. 
 So the answer is :  42000
