# The basic volume formulas that you should know about

Wondering what volume really is? Well, to define volume in its most basic form it is the three-dimensional space that a figure basically occupies. When you work on a **volume calculation**, you basically need to work using cubic units.

## Information on how to calculate volume

If you are interested in finding volume using **volume formulas**, then here is what you basically need to do:

## 1. Finding the volume of a cube

In order to calculate the volume of a cube with the help of a **formula volume**, it is necessary for you to know the length of at least one side of the cube. The basic formula that needs to be applied in order to calculate the volume of a cube is a^{3} or a x a x a wherein a = length of one side of the cube.

## 2. Finding the volume of a cylinder

The basic formula that is to be used for the **calculation for volume** for a cylinder is that of: pi x r^{2} x h. Herein, pi is a value that equal 3.14, whereas h is the height of the cylinder and r happens to be its overall radius.

## 3. Calculating the volume of a rectangular solid

If you are interested in calculating the volume of a rectangular solid, then **the formula for volume** that would apply here is that of: l x w x h. In this formula, l = length of the rectangular solid, w = width of the rectangular solid, and h = its standard height.

## 4. Finding the volume of a sphere

Considering that you have a sphere at hand and would like to learn **how to calculate volume** of a sphere, then the formula that you need to apply for the said purpose is that of (4 × π × r^{3})/3. As we already know, the value of pi = 3.14, whereas r is its radius.
