$\bf{ \red{Here \: is \: the \: answer !! }}$

1 helix = 34 A°

Each helix consists of 10 Nucleotide pairs (20 nucleotides)

34A° length of ds DNA = 20 nucleotides

length of ds DNA with 480 nucleotides= 480×34/20

length of DNA with 480 Nucleotides = 816 A°

Hence, the length of sample of ds DNA with 480 nucleotides is 816 angstrom (A°)
