. A certain sample of metal has a mass of 3 kg and a volume of 250 cm3. What is its density?

LekaFEV [45]

Given:

The mass of the sample is,

$m=3\text{ kg}$

The volume is

$V=250\text{ cm}^3$

To find:

The density

Explanation:

The volume is,

$\begin{gathered} V=250\text{ cm}^3 \\ =250\times10^{-6}\text{ m}^3 \end{gathered}$

The density is,

$\begin{gathered} d=\frac{m}{V} \\ =\frac{3}{250\times10^{-6}} \\ =12000\text{ kg/m}^3 \\ =12\times10^3\text{ kg/m}^3 \end{gathered}$

Hence, the density is

$12\times10^3\text{ kg/m}^3$
