According to the conditions of the problem:
V = 0.2 m ^ 3 – the volume occupied by oil;
m = 160 kg is the mass of oil;
It is necessary to find the density of the oil p.
Density is defined as the ratio of the mass of a substance to the volume occupied by this mass:
p = m / V = 160 / 0.2 = 800 kg / m ^ 3.
Answer: the density of oil is 800 kg / m ^ 3.
