## Explanation

The **volume** $V$ of a mass is the measure of the space it occupies. In physical and mathematical contexts, it is often expressed in cubic units.

### Formulae

For different geometric shapes, the volume can be calculated using specific formulae. Here are some examples:

**Volume of a Cube**

$V_{\text{cube}} = s^3$
where $s$ is the side length.

**Volume of a Rectangular Prism**

$V_{\text{rectangular\ prism}} = l \times w \times h$
where $l$ is the length, $w$ is the width, and $h$ is the height.

**Volume of a Sphere**

$V_{\text{sphere}} = \frac{4}{3} \pi r^3$
where $r$ is the radius.

**Volume of a Cylinder**

$V_{\text{cylinder}} = \pi r^2 h$
where $r$ is the radius of the base, and $h$ is the height.

### Importance in Science and Engineering

Understanding the concept of volume is **crucial** in fields such as physics, engineering, and chemistry, as it helps in determining the capacity, density, and displacement of materials.

In summary, the space displaced by a mass is **volume**, a fundamental concept with applications across various scientific disciplines.
