The total mass of all these objects can be determined by adding all the masses present in the question. 191.1 kg is the value of total masses when the given masses such as 56.9kg, 43.9kg, 60.5kg and 29.8kg are added with each other. This value is considered as the total sum of all masses so we can say that the total value is obtained after all the masses are combine or added together.
