Total kWH = power * time.

= 350 (watt) *24 (hour) *24 (days),
= 201600 watt hour,
= 201.6 kWH.

Kilowatt/Hour Means = ( 350 * 24 * 24)/1000.
= 201.6kwh.

KWh= (350*24*24)/1000
=201.6kwh.

1 day = 24 hours.

24 days = 576 hours.

KW H = P*TIME IN HOURS.

= 350*576 (We are used here 350 watts not a kw).

= 201600. Watt hours.

= 201600/1000.

= 201.6 KW H. IS ANSWER.
(1)

Because 1kW = 1000 W. So 201600 Watt hours is equal to 201.6 kWh.

Here, it is (use in watt * total hours)/1000.

P=9*120=1080WATT....... FOR UNITY pf.
FOR 20 MIN,
E=(1080*20)/1000 =21.6kwh.
