Question

What is the measure of the size of a body or region in three-dimensional space

Answer 1

Volume is how much space an object takes up. Mass is how much stuff is in that given space

Answer 2

Volume

Step-by-step explanation:

Volume is a three dimensional entity which measures the amount of matter contained within a body/object/substance.

The SI unit of volume is cubic meter (
`m^(3)`). For evaluating the volume of any shape at least three measurement lengths in three different directions are required except the circular/spherical shapes.

For example – Volume of Cube is equal to product of its side length in x, y and z direction. Since the length of side of cube (a) in all the direction is same, therefore its volume is equal to
`a^3`.

Volume of sphere is equal to
`(4)/(3) \pi r^(3)` where r is the radius of sphere.
