(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A rectangular metal plate measures 0.20 m long and 0.3 m wide. The plate is heated to a temperature of 1,433 K by passing a current through it. Assuming that it behaves like a blackbody, how much power does the plate radiate under these conditions?

2. Relevant equations

P∝T^4 (power is proportional to the temperature raised to the fourth power)

Only relevant equation I can find in my text book so far. I don't where to factor in the lengths in the question.

3. The attempt at a solution

Ive tried all sorts of combos of the equation i gave, but all of them are wrong. I have the same question with different numbers and the answer to that one but still dont know how to get it.ψ
