For this case, the first thing we must do is define variables.

We have then:

x: length of the bookshelf

y: thickness of each book

The equation for the number of books is:

N = \frac{x}{y}

Substituting values we have:

N = \frac{1.865 * 10 ^ 1}{9.3*10^{-2}}

Doing the calculation we have:

N = 200

Answer:

200 copies of this book will fit on the bookshelf
