A rectangular block of metal of density 8000kg/m^3 measures 2cm by 3cm by 10 cm. what is the mass of the block?

Sagot :

First, let's convert all dimensions to meters and then calculate the volume of the block, by multiplying all three dimensions of the block:

[tex]V=0.02\cdot0.03\operatorname{\cdot}0.1=0.00006\text{ m^^b3}[/tex]

Now, to calculate the mass, we multiply the density and the volume:

[tex]\begin{gathered} m=d\cdot V\\ \\ m=8000\cdot0.00006\\ \\ m=0.48\text{ kg} \end{gathered}[/tex]

Therefore the mass of the block is 0.48 kg.
