Question:

physics resistance help, thanks!?

The mass density of copper is 8920 kg/m3 . The resistivity of copper is 1.7 × 10?8 Ω · m . A sheet of copper is 7 mm thick and hassurface dimensions of 5 cm × 21 cm . If the long edges are joined to form a tube 21 cm in length, what is the resistance be-tween the ends? Answer in units of Ω.full stars for correct answer thanks :)

Answer:

Mass density of copper is an extra data not required to calculate resistance Required Resistance ((1.7*10^-8)*0.21)/(0.05*0.007) 0.1020 Ω.
