Density is the ratio of the substance's mass to volume. It is an extensive property, meaning it does not depend on the amount of the substance. The ratio is always fixed per identity of a substance. The density is equal to:

V = 2.9 cm x 3.5 cm x 10.0 cm = 101.5 cm³

Density = 615 g/101.5 cm³ = 6.06 g/cm³
