Start by multiplying 239 by 24

You get 5,736, this is how many watts are used per single day

Next multiply 5,736 by 8

You get 45,888, this is how many watts are used per 8 days, and is the final answer.
45,888 watts because 239 x 24 = 5,736 watts per day
 then you do 5736 x 8 = 45,888 watts used in 8 days
