what is volume and mass and how do u get mass and volume?

Answer 1

Volume - how much space something occupies

Mass - how much matter is in the object.

You get them by measuring them.

You can measure mass using a scale.

You can measuring volume by measuring the sides or by water displacement.

Answer 2

Volume is the quantification of how much space an object occupies in three dimensional space.

Mass is not so simple. Mass generally refers to how much matter is contained within an object irrespective of the volume it occupies.

Mass is often measured in weight, but that is relative to the observers position in three dimensional space and the gravity exerted by other objects in that space. Think of it as "the weight of any object is the measurement of gravitational force exerted upon it." so as you can see, weight is not equal to mass. Weight is a subjective term. Mass is objective and constant no matter where you are in space.

Mass can be computed in inertial mass, stationary mass, or a combination of both. Movement gives an object more inertia, which can be converted to extra mass with respect to the same object being stationary if the energy causing the motion is taken into account as part of the object.
