Germanium has a resistivity of 0.60 22. m. This material forms a rectangular box that is 16 cm x 4.8 mm x 4.8mm (16 cm long, 4.8 mm wide, and 4.8 mm high). What is the resistance of this box measured across its length? Suppose that you have two identical boxes like this. You combine them along a small square face, yielding a box that is 32 cm long. What is the resistance of this box measured across its length? Instead suppose that you combine them along a large rectangular face, yielding a sample that is 16 cm long, 9.6 mm wide, and 4.8 mm high. What is the resistance of this box measured across its length?
