First of all make sure you are ahead of your class course.
Complete 9th class biology course as soon as possible.
And then you may move to some fundamental biology books like Campbell biology.

Read my Blog here it contains details for your preparation and for the question refer to the Priyanshu’s answer.

You basically need to distance between two consecutive base pair, which is 3.4 A in B-DNA. Now, you can calculate accordingly.
