Imagine a graph with two axis, length and width. Each axis measuring one thing.
Now add another axis measuring another thing. You’re up to three dimensions on the graph.
Now, you’ll need to add a fourth to measure another thing. It’s completely possible mathematically, but it doesn’t really work with what we can intuitively understand. So it’s usually portrayed as a video of a 3d graph changing overtime.
A 5th axis is completely possible, but it’s even less intuitive than a changing the 3d graph over time. But it can be represented in numbers and processed easily by a computer.
This applies to any higher dimension as well.
