Answer:
[tex]2.38*10^{4}kJ[/tex]
Explanation:
One watt equals to 1 joule per second. So, one kilowatt equals 1 kilojoule per second. Thus, one kilowatt-hour is equivalent to:
[tex]1kWh=1\frac{kJ}{s}*3600s=3600kJ[/tex]
Finally, we can calculate the monthly electricity consumption in kJ:
[tex]6,619kWh*\frac{3600kJ}{1kWh}=2.38*10^{4}kJ[/tex]
