Calculate density of a rectangular solid, which has a mass of 25.71 g. it is 2.30 cm long, 4.01 cm wide and 1.82 cm high.

Density is a property of the substances that is obtained by dividing its mass by the volume. For a rectangular solid, the volume may be solved by the following equation,
 
                                          V = L x W x H

Substituting the given values for the dimension,
 
                  V = (2.30 cm) x (4.01 cm) x (1.82 cm) = 16.78786 cm³

Calculating for the density,
 
                                Density = mass / volume
 
                Density = 25.71 cm / 16.78786 cm³ = 1.53 grams per cm³

Thus, the density of the given solid is approximately 1.53 grams per cm³.
