Question

a. Calculate the density of a substance
whose mass is 10 kg and volume
is 2 m3.​

Answer 1

Answer:

10kg/2m³

the answer is 5kg/m³

Answer 2

Solution:

• The density of a substance whose weight is 10 kg and volume 2 metre cube is 5 kg m/s³

Explanation:

• We know that the formula to calculate density is

• ${\small{\underline{\boxed{\pmb{\sf{Density \: = \dfrac{Mass}{Volume}}}}}}}$

So here, we have to imply this formula to solve the whole question!

• We also know that the SI unit of density is kilogram per metre cube that is kg/m³ so after solution we have to add this unit too to make the solution perfect!

Provided that:

• Mass = 10 kg
• Volume = 2 m³
• Density = ???

Required solution:

$:\dashrightarrow \sf Density \: = \dfrac{Mass}{Volume} \\ \\ :\dashrightarrow \sf Density \: = \dfrac{10}{2} \\ \\ :\dashrightarrow \sf Density \: = \cancel{\dfrac{10}{2}} \: (Cancelling) \\ \\ :\dashrightarrow \sf Density \: = 5 \: kg/m^3$

• Therefore, density = 5 kg/m³
