The density of the earth is 3.51×10¹⁰ kg/m³
What is Density?
Density can be defined as the ratio of mass to the volume of a body. The S.I unit of density is kg/m³
To calculate the density of the earth, we use the formula below.
Formula:
- D = m/v............ Equation 1
Where:
- D = Denstiy of the earth
- m = Mass of the earth
- v = Volume of the earth
From the question,
Given:
Note: Since the earth is a spherical in shape, we can calculate the volume of the earth using the volume of a sphere
- v = 4πr³/3 = (4×3.14×6400000³)/3 = 1.71×10¹⁴ m³
Substitute these values into equation 1
- D = (6×10²⁴)/(1.71×10¹⁴)
- D = 3.51×10¹⁰ kg/m³
Hence, the density of the earth is 3.51×10¹⁰ kg/m³.
