To determine the density of books in a box, we need to know the formula for density. Density is generally defined as the amount of something per unit volume. Specifically, in this context:
1. Density ([tex]\(D\)[/tex]) is the number of books divided by the volume of the box.
Thus, the correct formula for calculating the density of books in the box would be:
[tex]\[ \text{Density} = \frac{\text{number of books}}{\text{volume of box}} \][/tex]
This formula correctly shows that density is the ratio of the number of books to the volume of the box, indicating how many books are present per unit volume of the box.
