Copper wire

What is the weight of 1000 m copper wire with a diameter of 5 mm when metric density p = 8.8 g/cm3?

Correct result:

m =  172.7876 kg

Solution:

l=1000 100=100000 D=5/10=12=0.5 r=D/2=0.5/2=14=0.25 p=8.8 V=π r2 l=3.1416 0.252 10000019634.9541 m=p V/1000=8.8 19634.9541/1000=172.7876 kg



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
