hope it would be helpful to you.

Answer 2

Explanation:

★ᏀᏆᏙᎬΝ:-

$\text{Mass of metal block}$$\implies 30kg$

$\text{Volume of metal block}$$\implies \sf 4 \: litres$

★Ꭲᝪ ᖴᏆᑎᗞ:-

$\text{Density of metal block.}$

★ន០ɭ⩏Ƭɨ០⩎:-

$\textsf{Formula to calculate Density when mass and volume is given,}$

$\boxed{\boxed{ \sf Density = \dfrac{Mass}{Volume}}}$

$\sf \orange{\underline{Using \: the \: formula:-}}$

$\boxed{\boxed{ \sf Density = \dfrac{30}{4}}}$

$\boxed{\boxed{ \sf Density = \dfrac{15}{2} \small kg/m^3}}$

Hope it helps.
