Question

F. Solve the following numerical problems.
1. Calculate the density of a solid of mass 20 kg if it occupies a volume of 4 m3.​

Answer 1

Mass=20kg

Mass=20kgVolume =4 m³

$since \: density = \frac{mass \: of \: the \: substance}{volume} \\ = > density = \frac{20}{4} \\ = 5 \frac{kg}{ {m}^{3} } \\ = 5kg {m}^{ - 3}$
