Enter the mass of object 1 (kg), the mass of object 2 (kg), and the mass of object 3 (kg) into the Average Mass Calculator. The calculator will evaluate and display the Average Mass. 

Average Mass Formula

The following formula is used to calculate the Average Mass. 

AM = (M1+M2+M3)/ 3

  • Where AM is the Average Mass (kg)
  • M1 is the mass of object 1 (kg) 
  • M2 is the mass of object 2 (kg) 
  • M3 is the mass of object 3 (kg) 

How to Calculate Average Mass?

The following example problems outline how to calculate Average Mass.

Example Problem #1

  1. First, determine the mass of object 1 (kg).
    • The mass of object 1 (kg) is calculated to be : 14.
  2. Next, determine the mass of object 2 (kg). 
    • The mass of object 2 (kg) is measured to be: 70.
  3. Next, determine the mass of object 3 (kg). 
    • The mass of object 3 (kg) is found to be: 50.
  4. Finally, calculate the Average Mass using the formula above: 

AM = (M1+M2+M3)/ 3

The values given above are inserted into the equation below and the solution is calculated:

AM = (14+70+50)/ 3 = 44.66 (kg)


Example Problem #2

The variables needed for this problem are provided below:

mass of object 1 (kg) = 8

mass of object 2 (kg) = 90

mass of object 3 (kg) = 10

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

AM = (M1+M2+M3)/ 3 = (kg)
