Answer:
1) Mass is the quantity of matter in a physical body. It is also a measure of the body's inertia, the resistance to acceleration when a net force is applied.
Mass = volume × density
1) Volume is the amount of space that a substance or object occupies, or that is enclosed within a container.
Volume=Mass/density
3) Density is the substance's mass per unit of volume.
Density=Mass/Volume
