Sure, I can help you with that! To insert a square symbol in a Word document, you can follow these steps:

1. Place your cursor where you want to insert the square symbol.
2. Click on the "Insert" tab in the top menu.
3. Click on the "Symbol" button in the "Symbols" section of the menu.
4. Select "More Symbols" at the bottom of the drop-down menu.
5. In the "Symbol" dialog box, select "Arial Unicode MS" as the font.
6. Scroll down until you find the square symbol you want to use (it should be near the bottom of the list).
7. Click on the square symbol to select it.
8. Click on the "Insert" button to insert the symbol into your document.
9. Close the "Symbol" dialog box.

Now you should see the square symbol in your document where you placed your cursor. To make it look like a footnote number, you can format it as superscript. Here's how:

1. Select the square symbol you just inserted.
2. Right-click on the selected symbol and choose "Font" from the context menu.
3. In the "Font" dialog box, check the box next to "Superscript" under the "Effects" section.
4. Click "OK" to close the dialog box.

Now your square symbol should be formatted as superscript, just like a footnote number. You can use this same process to insert and format the cubic symbol as well. Just select the appropriate symbol from the "Symbol" dialog box and format it as superscript using the "Font" dialog box.
