Imagine a bookshelf with a single row of books. This is a line, or the 1st Dimension. You need to know how many books from the side to count. So, if you have 100 books, you’ve found it after counting 10 from the left.
Next is a full book shelf. You need to know the which shelf it’s on then you need to know how many books to count in. This is the 2nd dimension. Your book is now on the 3rd shelf from the top, 10 books from the left.
Now, we move to a single story library with multiple rows of shelves. This is the 3rd dimension. You need to know which row your bookshelf is in, then which shelf it’s on, then how many to count in on the shelf itself. Here we have our book in the 12th row from the front, 3rd shelf from the top, 10th book in.
Finally, we have a multistory library. We first need to know which floor our row of bookshelves are. This is the 4th dimension (or our tesseract). You first go the the 2nd floor, move to the 12th row from the front, 3rd shelf from the top, 10th book from the left.
You could continue this by adding multiple library buildings, etc. to continue up the chain of dimensions. This isn’t a perfect analogy, but a good way to put multiple, dimensions into concept.
