Question

A piece of steel has a volume of 12cm^3 and mass of 96g.what is its density in kg/mcube?
​

Answer 1

Answer:

8000 kg per cubic metres

Explanation:

density = mass/ volume =( 96 /1000 )* (1000000/12) = 8000 kg per cubic metres

Answer 2

$\huge\tt\underline\red{Ans}\underline {w}\underline\purple{er}\underline{:}\orange{}$

$\huge \underbrace \mathfrak \red{\bigstar Explanation}$

${ \bold{ \underline{\purple{\underline{\large{Given : - }}}}}} \:$

$\tt V \:\:\:\:\:\:\:\:\:\:\:\:\:\: = 12cm³$

$\tt Mass \:\:\:\:\:\:\:= 96g$

$\tt Density = ?$

${ \bold{ \purple{\underline{\underline{\large{Solution : - }}}}}} \:$

Now, we know that :

$\tt \pink {\bigstar {\boxed{Density = \frac {Mass}{Volume} }\bigstar }}$

$\Longrightarrow Density = \frac {96g}{12cm³}$

$\Longrightarrow \:\:\:\:\:\:\:\:\:\:\:\:=\large { \frac {\cancel{96}g}{\cancel{12}cm³}}$

$\Longrightarrow \:\:\:\:\:\:\:\:\:\:\:\:\: = \large{\frac {8g}{cm³}}$

$\tt \pink{[As \:we \: know \: that\: ]}$

$\tt \green {\bigstar {\boxed{1g/cm³ = 1kg/m³} \bigstar}}$

$\therefore 8g/cm³ = 0.008g/m³ \: \: \: Ans$
