A piece of sugar has dimensions: a = 2.5 cm, b = 1 cm, c = 0.7 cm. Its mass is 3.2 g. Determine the density of sugar.

The density of a substance in physics is found by the following formula: ρ = m / V, where ρ is the density of a certain substance, m is the mass of a substance, V is the volume of a substance.
V = a * b * c = 2.5 cm * 1 cm * 0.7 cm = 1.7 cm ^ 3.
ρ = m / V = 3.2 g / 1.7 cm ^ 3 ≈ 1.88 g / cm ^ 3.
Answer: ρ = 1.88 g / cm ^ 3.
