Question

A metal ball weight 1.8 kg The volume
of the ball is 250cc.find the density
of
the metel​

Answer 1

Density of metal is 7.2×10³ kg/m³ or 7200 kg/m³.

Answer 2

$\sf\large\underline\red{Given:—}$

• Mass of the metal is 1.8 kg

• Volume of the metal is 250 cc

$\sf\large\underline\red{To\:find:—}$

find the density of the metal .

$\sf\large\underline\red{Solution:—}$

Volume of the metal = 250 cc = 1/4 L

We know that,

$\boxed{\bf{\blue{Density=\dfrac{Mass}{Volume}}}}$

$\sf{\implies Density = \dfrac{1.8}{\dfrac{1}{4}}}$

$\sf{\implies Density = \dfrac{18×4}{10}}$

$\sf{\implies Density = \dfrac{36}{5}}$

$\sf{\implies Density = 7.2\:kg/l = 7.2\:kg/m³}$

Therefore, density of the metal is 7.2 kg/m³

Additional information :-

$\sf\red{What\:is\:density\:?}$

Density is the degree of compactness of the particles. It is also defined as the mass per unit volume of a material.

$\sf\red{What\:is\:the\:SI\:unit\:of\:density\:?}$

The SI unit of density is kilograms per cubic metre (kg/m³)

$\sf\red{What\:is\:the\:formula\:of\:density\:?}$

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