In that case, if the body known indicators such as its volume (V) and density (p), the calculation of body weight required to use the formula: m = p* V.
2
For clarity, we can give you an example.Required to find weight of the concrete slab, whose capacity is 15 m³.
Solution: To find the weight of the concrete slab needs to know only his density .To find out this information, you need to use the table of densities of different substances.
3
According to this table concrete density of 2300 kg / m³.Then, in order to find weight of the concrete slab, need to make a simple algebraic operat
ion: m = 15 * 2300 = 34500 kg, or 34.5 tons.A: The weight of the concrete slab of 34.5 tons

mass measurement takes place in a conventional manner by means of one of the oldest instruments of mankind - with the help of weights.This is due to the body weight compared to using the standard weight of cargo - weights.
