Answer:
Given:-
The length of copper wire (L) = 270 cm
Area of cross-sectional (A) = 0.030 
and specific resistance (ρ) = 
ohm-cm.
Use the formula R=(Specific resistance*L)/A, to calculate the Resistance(R)
then, 
ohm
Simplify:
R = 0.0162 ohm = 
ohm
Therefore, the resistance of copper wire is, Ω
The percent is 56.
I worked it out by doing 140 divided by 250, then timesing the answer by 100.
I hope this answer helps!
