Do the math! The density of the earth p averages a little over5000kgm^3. Earth's radius R is greater than 6400km. Earth-HEOID-can be thought of as a ball. The volume of the ball V is: 4*3 14*R^3 3. Mass of a body is equal to p*V

The mass of the earth is equal to: M=p*V= 4 3 *p*pi*R^3* where R=6371 km is the average radius of the earth p= 5.51 g cm^3 is the average density of the earth M=4*5.51*10^3*3.14*6.371^3*10^18 3=6*10^24 kg
