How do we get the joules? what is the answer? please help...?

An electric motor on an airplane operates on 18.6 volts and draws a current of 13.3 amperes. How much energy (in joules) does the motor use during a 11 hour flight? Be careful of your units! The number will be quite large, so be careful when entering the number in the answer block. Double check your number before moving on.
