Question

Calculate the volume of wooden object of mass 280 kg, if density of wooden is 800 kg/m cube.
​

Answer 1

$\huge\rm\orange{Given:-}$

Mass = 280 kg

Density = 800 $kg/m^3$

$\huge\rm\orange{To~Find}$

Volume of the wooden object = ?

$\huge\rm\red{Solution}$

Formula to calculate volume :-

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

Put the values.

$\dfrac{280}{800}$

Cancel 1 zero from each no.

$\dfrac{28}{80}$

Both are divisible by 4.

(4×7=28)

(4×20=80)

$\dfrac{7}{20}$

$=0.35 m^3$

Answer ➣ Volume is 0.35 cubic metre.

Additional Information

Formula to calculate density

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

Formula to calculate mass

$Mass=Density×Volume$

The SI unit of density is $kg/m^3$

And the CGS unit is $g/cm^3$

The SI unit of mass is kg and CGS unit is g.

The SI unit of volume is $m^3$ and the CGS unit is $cm^3$

Answer 2

$\huge\underline{\underline{\bf\bigstar ANSWER \bigstar }}$

Given ,

Mass of wooden object = 280 kg

Density of wooden object = 800 Kg/m cube

$\longrightarrow \bf Volume = \dfrac{Mass}{Density }$

 $\sf \hookrightarrow Volume = \dfrac{280}{800}$

                  $=\dfrac{28}{80}$

                  $\bf = 0.35 \ m^2$
