To solve this problem we must consider the expressions of Stefan Boltzmann's law for which the rate of change of the radiation of energy H from a surface must be
Where
A = Surface area
e = Emissivity that characterizes the emitting properties of the surface
= Universal constant called the Stefan-Boltzmann constant
T = Absolute temperature
The total heat loss would be then
Therefore the net rate of heat loss from the body by radiation is 155.29J
