    Answer: it consumes 5040 watt hour in 3 days and 12 hours

    Step-by-step explanation:

    light bulb consumes 1440 watt hours per day. The number of hours in a day is 24. This means that the consumption of the light bulb per hour would be

    1440/24 = 60 watt hour.

    The consumption for 12 hours would be

    60 * 12 = 720 watt hour.

    The consumption for 3 days would be

    3 * 1440 = 4320 watt hour

    The total consumption in 3 days and 12 hours would be

    4320 + 720 = 5040 watt hour
