Using MS Excel; solve the temperaluro distribution for the aluminum plate described in the lable

and figure below. Assume the plate thickness to be $1$ cm $($in $Z$ direction$)$ and the heat transfer to

be in the XY plane only, similarly to the circuit board example we covered in class. Assume the

thermal conductivity of aluminum to be $237\frac{W}{m}C.$
