Can the following equation be used to solve the question?
R = ρ L / A ; find L.. or is there another way?
Question: A rectangular piece of gold is 2.2 cm long and 2.4 cm wide. How deep is the piece when it displays a resistance of R = 1.06 μω for a current that flows along the depth-direction?

Hi, thanks for answering.
Apparently our professor wants us to do this question without using density. Is there another possible way to solve this question that you can direct me to?

ρ is not density in this case. Refer to Table 14.3 on page 455 in the textbook, it states the resistivity value of gold.
