Homework Statement
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?
Homework Equations
P∝T^4 (power is proportional to the temperature raised to the fourth power)
Only relevant equation I can find in my textbook so far. I don't where to factor in the lengths in the question.
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 don't know how to get it.ψ
