A rectangular piece of gold is 3.6 cm long and 3.5 cm wide. How deep is the piece when it displays a resistance of R = 1.51 ìù for a current that flows along the depth-direction?

---

p is found in a table...right?

and then..

R=pl/A

R=pl/(2dw+2wl+2dl)

then solve for d...

i did this but got the answer wrong..where am i making mistakes???
