Surface temperature of earth

127. Calculate the temperature (K) of the earth if there were no greenhouse effect. Assume the solar irradiance is 1500 W/m2 and the total planetary
albedo is 25 percent. (The Stefan Boltzmann constant is 0.567e-07 W/m2/K4). ****I've tried to answer this twice, but both times I was incorrect and the program gave the following hint (which was NO help whatsoever): Stefan Boltzmann law ****Please do this only if you're 100% sure you're right. The program is very picky! Thanks :)
