Question

An object has a mass of 420 kg and a volume of 7 m3. Find the density of the object in kg/m3.

Answer 1

$\huge\fcolorbox{red}{cyan}{60\:kg/m³}$

Step-by-step explanation:

• Mass = 420 kg
• Volume = 7 m³
• Density = ?

$\bf\color{purple}{Density=\frac{Mass}{Volume}} \\ => \bf{Lets\:Put\:The\:Values} \\ => \frac{420}{7} \\ => \boxed{60}$

Hope it helped

Answer 2

As we all know, the data used to answer the above question is as follows.

An object with a mass of 540kg.

In addition, the object's volume is$7m^{3}$.

Therefore the density of the object must be determined.

we must use the formula of density equals mass divided by volume.

As a result, the object's density is,

$density = \frac{mass}{volume}$

$d = \frac{420}{7}$

Solving the equation further we get,

$d=60kg/m^{3}$

Hence the density of the object is 60$\frac{kg}{m^{3} }$
