Answer:
Number of nucleosomes in  bp is equal to
bp is equal to 
Explanation:
For wounding one nucleosome, total length of DNA required is equal to  bp
 bp
The length of  linker DNA in mammals is equal to  bp
 bp
Thus , the total length of DNA that confides between two nucleosome is equal to the sum of wounding length of DNA and the linker length
 bp
bp
Thus, in  bp length of DNA, the total number of nucleosomes is equal to
bp length of DNA, the total number of nucleosomes is equal to 
Thus, number of nucleosomes in  bp is equal to
bp is equal to
