T = 1152K

Explanation:

According to Stefan-Boltzman's law*

P = sigma epsilon AT^4

rArr T^4 = P/(Asigma epsilon)

Givens:
epsilon =1 for a blackbody

P/A = 1 W"/"cm^2 = 10^4W/m^2

sigma = 5.67xx10^(-8) W/(m^2K^4)

T^4 =(10^4 W/m^s)/(5.67xx10^(-8) W/(m^2K^4) ) = 1.764xx10^12 K^4

T =root(4)(1.764xx10^12 K^4) = 1152K
