A body with a volume of 0.2 m3 consists of a substance with a density of 5000 kg / m3. What is the body weight?

V = 0.2 m ^ 3.
ρ = 5000 kg / m ^ 3.
m -?
According to the definition, the density of a substance ρ is the ratio of its mass m to the volume V that this substance occupies.
ρ = m / V.
Let us express the body mass from the formula: m = ρ * V.
m = 5000 kg / m ^ 3 * 0.2 m ^ 3 = 1000 kg.
Answer: body weight m = 1000 kg.
