The space occupied by the object is called _________.

Hint:The matter is all the total amount that exists in the universe. Everything you can see and touch is made of matter, including us. The only things that don’t matter are forms of energy, such as light and sound. In science, the matter is defined as anything that has mass and volume. Mass and volume measure different aspects of the matter.

Complete step by step answer:
Volume is a measure of the amount of space that a substance or an object occupies. The basic SI unit for volume is the cubic meter (${m^3}$ ), but smaller volumes may be measured in $c{m^3}$, and liquids may be measured in liters ($L$) or milliliters ($ml$). The volume of matter is measured depending upon its state.

A measurement container, such as a measuring cup or graduated cylinder, measures the volume of a liquid. A gas’s volume depends on its container's volume: gases expand to fill whatever space is available to them.

From its dimensions, the volume of a regularly formed solid can be determined. For example, the volume of a rectangular solid is the product of its length, width, and height.

A sphere is a three-dimensional circle. We need to know the radius ($r$) in order to measure either the surface area or the volume of a sphere. The radius is the distance from the middle of the sphere to the tip, and no matter what points on the tip of the sphere we calculate from, it is always the same.

By the displacement process, the volume of an irregularly formed solid may be determined.

Note:
-The volume of a rectangular room can be calculated with the formula:
  Volume = length × width × height
-Mass is a measure of a material or an object's volume of matter.
-A kilogram ($kg$) is the basic SI unit for mass, but smaller masses can be measured in grams ($g$).
