| **How many times is the mass of a piece of marble with a volume of 3 m3 greater than the mass of paraffin of the same volume?**

Let us compare the density of marble ρm = 2.6 g / cm³ with the density of paraffin ρp = 0.9 g / cm³.

2.6 / 0.9 = 26/9 ≈ 3.

ρ = m / V.

Since the mass of a body is directly proportional to its volume, the mass of a piece of marble is approximately 3 times greater than the mass of paraffin of the same volume.

Answer: 3 times.
