Answer
mass = 9 g/cm³ * 72 cm³ = 648 g.
Explanation
Physically, density is the mass per unit volume of the substance, mathematically calculated by the formula: Density = mass/volume. We now have density and volume and you are asked to find out the mass of the cuboid. By rearranging the formula, we get mass = Density × volume.
