Space occupied by matter
The space occupied by matter is known as volume. It is the amount of three-dimensional space that an object occupies. Volume is a fundamental property of matter and is often measured in cubic units such as cubic meters or cubic centimeters.

Importance of volume
Volume is an essential concept in physics, chemistry, and engineering. It is used to describe the size, shape, and quantity of objects. Understanding the volume of matter is crucial for various calculations and experiments.

Measuring volume
Volume can be measured using different methods depending on the shape of the object. For regular shapes like cubes or spheres, the volume can be calculated using specific formulas. For irregular shapes, techniques such as water displacement or using a graduated cylinder can be employed to determine the volume.

Units of volume
Volume is typically measured in cubic units such as cubic meters (m3) or cubic centimeters (cm3). These units represent the amount of space that an object occupies in three dimensions. Other common units of volume include liters and gallons, which are used for measuring liquid volumes.

Conclusion
Understanding the concept of volume is crucial for various scientific disciplines. It allows us to quantify the amount of space occupied by matter and make accurate calculations in experiments and real-world applications.

The space occupied by matter is called it's volume.
