A piece of sugar has dimensions: a = 2.5 cm, b = 1 cm, c = 0.5 cm. Its mass is 0.32 g. Determine the density of sugar.

a = 2.5 cm = 0.025 m.
b = 1 cm = 0.01 m.
s = 0.5 cm = 0.005 m.
m = 0.32 g = 0.32 * 10 ^ -3 kg.
ρ -?
The density of the substance ρ is the ratio of the mass of the substance m to the volume of the substance V it occupies: ρ = m / V.
A piece of sugar has the shape of a rectangular parallelepiped, so its volume V will be determined by the formula: V = a * b * c.
ρ = m / a * b * c.
ρ = 0.32 * 10 ^ -3 kg / 0.025 m * 0.01 m * 0.005 m = 256 kg / m ^ 3.
Answer: the density of sugar is ρ = 256 kg / m ^ 3.
