A body with a volume of 20m consists of a substance with a density of 7.3g / cm. what is the body weight?

The formula for finding body weight is:
m = p * V,
where m is body weight, kg;
p – body density, kg / m3;
V – body volume, m3.
According to the International System of Units (SI), the unit of measure for density is kg / m3.
Based on this:
p = 7.3 g / cm3 = 7300 kg / m3.
Substituting into the formula, we get:
m = 7300 * 20 = 146000 kg.
Answer: Body weight is equal to m = 146000 kg.
