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?
4 answers
That is the way.
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.
sick you knew the textbook we're using
