Pieces of zinc and paraffin marble have the same mass, which can be said about the volume.

V = m / ρ. With the same mass m, the greater the density ρ of the substance, the smaller the volume V. Paraffin has the lowest density (0.88-0.915 g / cm * 3), which means it will have the largest volume. Marble has a higher density than paraffin, but less than zinc (2.7 g / cm * 3), which means its volume will be less than that of paraffin, but more than that of zinc. The highest density zinc (7.133 g / cm * 3) will have the smallest volume.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
