There is no need to welcome you to the 3 Dimensional world, because you might as well be sitting in it. However, our universe technically exists in four dimensions, the fourth dimension being time; a Temporal Dimension and not a Spacial Dimension. This simply means that time does not take up mass or volume but can still be measured and applied to normal volume form. For example, time can be combined with the first 3 dimentions to form "Spacetime." Unfortunately, as solid objects, we can only be physically measured in 3 Dimensions:

### Volume = Length x Width x Height

## V = S^{3}

These familiar formulas help us find the volume (the amount of space an object occupies) of a 3 Dimensional object.
