Question

A block of metal has a mass of 20,000kg and a volume of 4m3. What is its density

Answer 1

Provided that:

• Mass = 20,000 kg
• Volume = 4 m cube

To calculate:

• The density

Solution:

• The density = 5000 kg m³

Using concept:

• Density formula

Using formula:

• D = M/V

Where, D denotes density, M denotes mass and V denotes volume.

Required solution:

»»» Density = Mass/Volume

»»» D = M/V

»»» D = 20,000/4

»»» D = 5,000 kg m³

»»» Density = 5,000 kg m³

$\begin{gathered}\boxed{\begin{array}{c}\\ {\pmb{\sf{Some \: formulas!}}} \\ \\ \sf \star \: Density \: = \dfrac{Mass}{Volume} \\ \\ \sf \star \: Volume \: = \dfrac{Mass}{Density} \\ \\ \sf \star \: Density \times Volume = Mass \end{array}}\end{gathered}$

Answer 2

Question:

• A block of metal has a mass of 20,000 kg and a volume of 4m³. What is its density

Answer:

• The density of the metal block is 5000kg/m²

Explanation:

Given that:

• A block of metal has a  mass of 20,00kg
• The block has a volume measuring  4m³

To Find:

• The measure of the density of the block

Formula Used:

$\bigstar \; {\underline{\boxed{\bf{ Density = \dfrac{Mass}{Volume} }}}}$

Required Solution:

• Using equation to find density

★ We know that ,  

${\blue{\bigstar{\underline{\boxed{\bf{D_{(Density)} = \dfrac{M_{(Mass)}}{V_{(Volume)}} }}}}}}$

★  Where ,

• Density is the package of the molecules in volume by an object , i.e ; Mass per Unit Volume

• Mass is defined as the quantitative measure of inertia
• Volume is the space occupied by and object  

According to the question:

• The object in the above case is considered to be the block .We also have the measure of the volume and the Mass so , let's substitute the values in the formula above and find the density of the block

⠀⠀⠀⠀⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━

Substituting the values:

➻ $\blue{\bf {D_{(Density)} = \dfrac{Mass}{Volume}}}$

➻ $\orange{\bf{D_{(Density)} = \cancel\dfrac{20000kg}{4m^3} }}$

➻ $\red{\bf{D_{(Density)} = 5000kg/m^3 }}$  

★  Henceforth ,

• The Density of the object is 5000 kg/m ³

Therefore:

• The density of the metal block measures 5000 kg/m³
