An objest has a mass of volume 3 cubic metre and density 6000 kilogram per cubic metre .What is its mass?

Answer 1

Dear Student,


$$\begin{gathered} \mathrm{Density}=\frac{\mathrm{mass}}{\mathrm{Volume}} \\ \mathrm{or},\mathrm{Mass}=\mathrm{Density}\times \mathrm{Volume} \\ \mathrm{or},\mathrm{Mass}=6000\mathrm{kg}/{\mathrm{m}}^3\times 3{\mathrm{m}}^3=18000{\mathrm{kg}}^{} \end{gathered}$$
