Answer:

Step-by-step explanation:

3000 W = 3 kW

3 kW(4hr/day)(30 day/month) = 360 kWh/month

360 kWh/month($0.15 / kWh) = $54

So about $75 when you add all the taxes and other fees that get added to a typical electric bill.

Nezavi [6.7K]

Answer: Ok so I may be wrong but I got 84ft

Step-by-step explanation: The bottom looks like a rectangle so it would be 4 times 12. 4 times 12 equals 48. since the height is 4 it would be 10-4 which equals 6. 6 Times 12 divided by two equals 36. 36 plus 48 is 84.
