9,158,960km^2 = 9,158,960*10^6 m^2 =
9.159*10^12 m^2.
m^2 * (kJ/m^2)/h = Total kJ/h.
Consider a cloudless day when the sun shines down across the United States. If 2375 kJ of energy reaches a square meter (m2) 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 km2.
I am having serious trouble with this one. I do not want the answer, but I need more help then just a formula. maybe change the numbers and solve a similar problem for me?
