If the substance has 8,900 kg of mass in each m³ of it, then it must follow that 2.8 m³ of it must have (2.8 * 8,900) = 24,920 kg of mass.
Mass is the measure of how many constituent particles are present in a unit area of a substance. The mass of copper present in 2.8 cubic meter area is 24,980 kg.
Mass:
It is the measure of how many constituent particles are present in a unit area of a substance.
Given Here,
Density of Copper = [tex]\bold {8900 kg/m^3}[/tex]
Mass of of copper in [tex]\bold {2.8\ m^3}[/tex] are = ?
Density of copper means 8900 kg of copper is present in per cubic meter area.
So, copper present in 2.8 cubic meter area,
[tex]\bold {8900\ kg/m^3 \times\bold {2.8\ m^3} = 24,980\ kg}[/tex]
Therefore, the mass of copper present in 2.8 cubic meter area is 24,980 kg.
