Cutting up yellow squash

I am cutting up some yellow squash for a new casserole I made last week. This is my first time, so I am measuring everything to see how much volume each item takes up. The recipe I found online is merely a starting point. You don't really think I'll blindly follow someone else's instruction, do you? I have my own ideas and will combine and modify recipes as I see fit, until I get the results I want.

 

There will be several more photos in this series.
