Calculate the resistance between opposite faces

Reference no: EM13645924

My teacher hasn't gone over chapter 17 yet, and we have aproblem set due tomorrow. There are 4 questions I couldn'tdo, but this one I don't even know where to start:

(a) A 115-g mass of aluminum is formed into a right circularcylinder, shaped so that its diameter equals its height. Calculate the resistance between the top and bottom faces of thecylinder at 20oC.

(b) Calculate the resistance between opposite faces if thesame mass of aluminum is formed into a cube.
