The power is multiplied by time then the energy is:
E = P*T.
E = 400*30 = 12*10^3.
= 12KWH.
E = P*T.
E = 400*30 = 12*10^3.
= 12KWH.

1000 watt = 1kW.
400watt for 30h = 400*30 = 12000Wh = 12kWh.
400watt for 30h = 400*30 = 12000Wh = 12kWh.

P = 400.
T = 30
:PT = 12000.
PT/1000.
= 12.
T = 30
:PT = 12000.
PT/1000.
= 12.

E = 12 kWh.
E = 400*30 = 12000.
E = 12 kWh.

p=400w, time=30.
400*30=12000wh=12kwh.
400*30=12000wh=12kwh.

1000 watt = 1 kw.
400*30/1000 = 12 kwh.
400*30/1000 = 12 kwh.

400*30 = 12000,
12000/1000 = 12kwh.
12000/1000 = 12kwh.
