There's no need to carry along the non-relevant pages for this project, so you might want to work smartly and utilize Acrobat's Extract Pages command to isolate your needed pages from the rest.
To use this powerful command, you can access it from the document menu (Document > Extract Pages) or directly from the Pages Panel.
In this example, I have highlighted pages 8-10 in a PDF. I then right-clicked on one of the highlighted pages and selected Extract Pages from the context menu.

The next dialog box asks for specific page extraction options. I can specify a different page range, designate whether the extracted page(s) should remain in the original, or deleted after the process, and even whether multiple pages should be each extracted as individual files or not.
Once the extraction is performed, the end result is a new PDF file, consisting of only the pages to which the Extract Pages command were applied. This new file will be titled "Pages from {original file}.pdf". Handy, convenient, and a feature that's been in Acrobat as far back as I can remember.
