Question

Bola, who weight. 150 pounds. found a rock .What is
density of a rock if its mass
is 36g and irs
volume is 12 cm3?​

Answer 1

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\tt{\therefore{Density=3\:g/cm^{3}}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green{\underline \bold{Given :}} \\ \tt: \implies Mass \: of \: rock = 36 \: g \\ \\ \tt: \implies Volume \: of \: rock = 12 \: {cm}^{3} \\ \\ \red{\underline \bold{To \: find :}} \\ \tt: \implies Density \: of \: rock( \rho) = ?$

• According to given question :

$\bold{As \: we \: know \: that} \\ \tt: \implies Density = \frac{Mass}{Volume} \\\\ \tt: \implies Density = \frac{36}{12} \times \frac{g}{cm^{3} } \\ \\ \green{\tt: \implies Density = 3 \: g/cm ^{3}} \\ \\ \bold{For \: density \: in \: SI \: unit : } \\ \tt: \implies Density = 3 \times \frac{1000000}{1000} \times \frac{kg}{ {m}^{3} } \\ \\ \green{\tt: \implies Density =3000 \: kg/{m}^{3} }$

Answer 2

$\red{\underline{\underline{\bold{Answer:}}}}$

$\purple{\tt{\therefore{Density=3\:g/cm^{3}}}}$

$\orange{\bold{Step-by-step\:explanation:}}$

• Given :

➠ Mass of rock = 36 g

➠ Volume of rock = 12 cm^{3}

• To find :

➠ Density = ?

• According to given question :

$\bold{\green{By \: the \: formula\:of \: density}} \\ \pink{ \implies Density = \frac{Mass}{Volume}} \\\\ \orange{\implies Density = \frac{36}{12}} \\ \\ \purple{\implies Density = 3 \: g/cm ^{3}}$
