Consider a cloudless day on which the sun shines down across the United States. If 2014 kJ of energy reaches a square meter( m 2) of the United States in one hour, how much total solar energy reaches the entire United States per hour? The entire area of the United States is 9,158,960 km 2 .

Explanation:

1) Radiation's ratio: 2014 kJ/m²

2) United States' area:  is 9,158,960 km² .

3) Formula:

4) Conversion factor:

5) Solve:

In one hour:

That is per hour.

The answer is rounded to 4 signficant figures.
