Chapter 25, Problem 22P

(II) A rectangular solid made of carbon has sides of lengths 1.0 cm, 2.0 cm, and 4.0cm, lying along the x, y, and z axes, respectively (Fig. 25–35). 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 ρ = 3.0 × 10-5 Ω·m.
