Assume that the total surface area of a human body is $1.6 \mathrm{~cm}^{2}$ and that it radiates like an ideal radiator. Calculate the amount of energy radiated per second by the body if the body temperature is $37^{\circ} \mathrm{C}$. Stefan constant $\sigma$ is $6.0 \times 10^{-8} \mathrm{~W} / \mathrm{m}^{2}-\mathrm{K}^{4}$.
