A rectangular solid made of carbon has sides of lengths 1.0cm, 2.0cm, and 4.0cm, lying along the x,y, and z axes. respectively. Determine the resistance for current that passes through the solid in (a) the x direction, (b) the y direction, and (c) the z direction. Assume the resistivity is p = 3.0*10^-5 Ohm x m.
