    In order to calculate the density of the rectangular book, first, we have to determine the concept of density. Density is a measure of compactness of a material or a substance. It is the relationship between the mass of the substance and how much space it takes up. To solve for the density we have to determine both the volume and the mass of the book. From the given condition, we can compute for the volume of the book which is a rectangular prism by obtaining the product of its length, width, and heigh (L x W x H). V = L x W x H V = (3.0 cm) (2.0 cm) (4.0 cm) V = 24.0 cu. cmAfter computing for the volume, we can calculate the density by dividing the mass of the book by its volume. Density = 120 g / (24.0 cu. cm) Density = 5 g/cu. cmBy the calculations above, we have calculated the density of the rectangular book to be 5 g/cu. cm.
