What is Density
Density is an important property of any material. Density is defined as mass per unit volume. We use Greek letter ρ (rho) for density.
if m is the mass of homogeneous material of volume V then. The density ρ would be given by
ρ=massVolume=mv
Density is a positive scalar quantity
SI unit of Density is Kg/m3. CGS unit of density is g/cm3
Some Unit conversions 1m3=103L 1m3=106cm3 1L=103cm3
Example of Few questions where you can use this Density Calculator Question 1
A Body of mass 4 kg have volume 10m3.Find the Density ? Answer
Given , m= 4 kg, V=10m3, ρ =?
Density is given by ρ=massVolume=mV ρ=410=.4Kg/m3
Question 2
A object has density as 10kg/m3. The volume is 3m3. Find the mass of the body. Answer
Given , m= ?, V=3m3, ρ=10kg/m3
Density is given by ρ=massVolume=mV
Rearranging this
m=ρ×V=10×3=30kg Question 3
A object has density as 20kg/m3. The mass is 2 kg. Find the Volume. Answer
Given , m= 2 kg, V=?, ρ=20kg/m3
Density is given by ρ=massVolume=mV
Rearranging this
V=mρ=220=.1m3
How the Density Calculator works
1. If mass and volume given ρ=mV
2. If mass and density are given V=mρ
3. If volume and density are given m=ρ×V
