Find the density, in g/cm3, of a metal cube with a mass of 50.3 g and an edge length (l) of 2.65 cm. the volume (v) of a cube is v=l3

Respuesta :

Density is a physical property which describes the mass of a substance per unit of volume of the substance. It is expressed as Density = m / V. We calculate as follows:

Density = m / V

V = volume of a cube = (edge length) ^3 = (2.65 cm) ^3 = 18.61 cm^3

Density = 50.3 g / 18.61 cm^3 = 2.70 g / cm^3
