V = a x b x c

V = 2.30 x 4.01 x 1.82

V = 16.78586 cm³

D = m / V

D = 25.71 / 16.78586

D = 1.53 g/cm³

Density is a value for
mass, such as kg, divided by a value for volume, such as m3. Density is a
physical property of a substance that represents the mass of that substance per
unit volume. Calculation is as follows:

Density = mass / volume = 25.71 g / (
2.30cm x 4.01 cm x 1.82 cm)
Density = 1.53 g/cm^3
