Problem 01. The relation between energy density and emissivity

The problem asks you to
prove the relation between the energy density in a cavity and the emissive power (Equation 1-1).
The problem provides (assumes)
isotropic radiation
You should know about
1) the definition about the energy density and the emissive power
2) the volume integration about spherical coordinates
