Given :
The energy consumed by the house in a month = 215 units = 215 kWh.
We know that 1 kWh = 3.6 × 10^8 J
So the energy consumed by the house in joules =
= 215 × 3.6 × 10^8
= 774 × 10^8
= 7.74× 10^10 joules.
Definition of 1 kWh :
Energy consumed in 1 kWh if a machine or appliance of 1 kilowatt power is operated for a period of 1 hour.
