What is the number of DNA strands per cell?
Human cells contain 23 pairs of chromosomes (46 chromosomes in total).
Each chromosome is formed by 2 strands of DNA tied by hydrogen-bonds to each other making the classic  DNA double helix (double-stranded DNA). So, in total there are 46*2=92 strands of DNA in each diploid human cell! Gametes contain half of the chromosomes, so half of the strands as well.
