A box with a volume of 30cmx45cmx20cm is filled with refined sugar. Its weight is 43.2 kg. What is the density of sugar?

Initial data: the volume of the box with refined sugar 30 cm x 45 cm x 20 cm (0.3 mx 0.45 mx 0.2 m); m (weight of refined sugar in a box) = 43.2 kg.

The density of refined sugar can be determined by the formula: ρ = m / V = m / (a * b * c).

Let’s make a calculation: ρ = 43.2 / (0.3 * 0.45 * 0.2) = 1600 kg / m3.

Answer: The density of refined sugar is 1600 kg / m3.
