If a light bulb uses 60 joules of energy every second, how much energy (in joules - J) will that light bulb use in one week?

36,288,000.

Explanation:

60 x 60 = 3,600

That will give u the amount of joules per minute.

3,600 x 60 = 216,000

That will give u the amount of joules per hour.

216,000 x 24 = 5,184,000

That will give u the amount of joules per day.

5,184,000 x 7 = 36,288,000

That will give u the amount of joules per week.
