8.5 cm cable weighs = 52 grams
1 cm of cable weighs = [tex] \frac{52}{8.5}grams[/tex]
= [tex]52/ \frac{85}{10} [/tex] grams
= [tex]52* \frac{10}{85} [/tex] grams
= [tex] \frac{520}{85} [/tex] grams
= [tex]6.11764[/tex] grams
Rounding it up = 6. 10000 grams
Then,
10 cm of cable weighs = [tex]6.10*10[/tex] grams
= [tex]61.0[/tex] grams
