Initial data: V (volume occupied by an unknown substance) = 15 m ^ 3; m (mass of unknown substance) = 15 tons.

SI system: m = 15 t = 15 * 10 ^ 3 kg.

Let’s determine the density of an unknown substance by the formula: ρ = m / V = 15 * 10 ^ 3/15 = 1 * 10 ^ 3 kg / m ^ 3 = 1000 kg / m ^ 3 (fresh water density).

Answer: The unknown substance is fresh water (ρ = 1000 kg / m ^ 3).
