R=[tex]\epsilon[/tex][tex]\sigma[/tex]T[tex]^{4}[/tex]

[tex]\epsilon[/tex] --> emmisivity
[tex]\sigma[/tex] --> Steffan's constant
T[ --> Temp (in Kelvin)

should i start with steffan-boltzmann's equation (since its the nearest formula)?

thanks... ^_^

Actually, I think that already is the Stefan-Boltzmann law; if you start from it you're done.

There is a derivation here, though generally I always check derivations on Wikipedia before I trust them
