Answer:

46.08KJ

Step-by-step explanation:

Given the power needed to light one bulb is 32W

We know that Power=energy/time

Therefore the energy needed to light one bulb is
power*time

Given time= 1minute= 60 seconds.

Energy =
32W*60sec = 1920J

energy recquired to light one bulb is 1920J

The energy recquired to light 24 bulbs is =
24*1920J=46080J=46.08KJ
