Answer: 1: The weight is the total amount of force that is required to accelerate any object with its mass. Whereas, the mass is the actual amount/ numerical measurement of the weight that the object has in it. And the volume is basically the 3D space an object occupies around itself.
2: The three ways of determining volume of an object are as follows:
a) Make the use of space : Measuring the physical dimensions of different quantities.
b) Use of Density and Mass: The formula; Volume= Mass/Density
c) Use the Displacement value: Measure the volume of the object which is displaced as soon as the object gets immersed in any gas or liquid.
