Question

A piece of lead weight 232 gram and has a volume 20 cm cube. Find the density of cube?​

Answer 1

Given :- A piece of lead weighs 232 g

⠀⠀⠀⠀⠀Its volume is equal to 20 cm³

⠀

To Find :- The density of the lead.

⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁

⠀⠀

Solution:-

We know that ;$~~ \color{purple}{ \: {\sf \: Density = \dfrac {Mass}{ V olume } \: \:} \: }$

⠀⠀⠀⠀⠀⠀⠀

$\sf Mass \: of \: lead \: (M) = 232 \: g$

⠀⠀⠀⠀⠀⠀⠀

$\sf \: \: \: \: :\implies Volume \: of \: lead \: (V) = 20 cm³$

⠀⠀⠀⠀⠀⠀⠀

$\: \: \: \: \: \: \: :\implies\sf Density \: of \: lead \: = \: \dfrac{M}{V}$

⠀⠀⠀⠀⠀⠀⠀

$\: \: \: \: \: \: \: \: \: :\implies\sf\dfrac{232 \: g}{20 \: cm²}$

⠀⠀⠀⠀⠀⠀⠀

$\: \: \: \: \: \: \: \: \: \: \: \: :\implies\sf 11.6~g/cm^3$⠀

⠀⠀⠀⠀⠀⠀

${ {\underline{ \purple{\sf{ \therefore \: The \: density\: of \: the \: lead = 11.6\;g/cm^3}}}}}$

Answer 2

Given :- A piece of lead weighs 232 g

⠀⠀⠀⠀⠀Its volume is equal to 20 cm³

⠀

To Find :- The density of the lead.

⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁

⠀⠀

Solution:-

We know that ;$~~ \color{purple}{ \: {\sf \: Density = \dfrac {Mass}{ V olume } \: \:} \: }$

⠀⠀⠀⠀⠀⠀⠀

$\sf Mass \: of \: lead \: (M) = 232 \: g$

⠀⠀⠀⠀⠀⠀⠀

$\begin{gathered} \sf \: \: \: \: :\implies Volume \: of \: lead \: (V) = 20 cm³ \\ \end{gathered}$

⠀⠀⠀⠀⠀⠀⠀

$\: \: \: \: \: \: \: :\implies\sf Density \: of \: lead \: = \: \dfrac{M}{V}$

⠀⠀⠀⠀⠀⠀⠀

$\: \: \: \: \: \: \: \: \: :\implies\sf\dfrac{232 \: g}{20 \: cm²}$
