🤓 Based on our data, we think this question is relevant for Professor Li's class at FIU.

Solution: You are given a copper bar of dimensions 3 cm x 5 cm x 8 cm and asked to attach leads to it in order to make a resistor. If you want to achieve the SMALLEST possible resistance, you should attach the leads to the opposite faces that measure (a) 3 cm x 8 cm. (b) 5 cm x 8 cm. (c) 3 cm x 5 cm. (d) Any pair of faces produces the same resistance.
