Again, all the math should be written in LATEX. Don't attach a picture with mathematics. If there's a derivation you wish to discuss, then write it all here using LATEX.

You have to use the differential form when the integral form can not give you the answer. For instance, you may need it when trying to find $q^"$ just near the surface for a solid with a non-constant thermal conductivity.

Hint: you don't need the data left of the block or within the block to find (a) or (b). You only need the temperature on the right side of the block. Think about it more.

Because $h_1$ is not given in the question statement, it is not needed to solve the problem. Once (a), (b), (c), and (d) are found, you can find $h_1$ if you wish, but that is not necessary.

You can assume the convective heat transfer within the filler fluid to be included within the contact resistance itself (the contact resistance will be smaller in case there is more convective heat transfer).
