## Homework Statement

A power plant burns coal and generates an average of 700.0 Megawatts (MW) of electrical power while discharging 1162.00 MW as waste heat. Find the total electrical energy generated by the plant in a 30-day period.

## Homework Equations

W = J/sec

## The Attempt at a Solution

Total of, 1862 MW, which are 1.862x10^9 W.

In 30 days there are 2.592x10^6 seconds.

So,

1.862x10^9 * 2.592x10^6 = 4.826x10^15 J.

I don't know why it's incorrect. This is a question from an online learning system, and it tells me this answer is wrong. Would love some help.
