Android Cooked folder size vs final apk size

Hey guys, Anyone can help me to understand the relation between cooked folder in the saved folder and final APK?
I mean, why the size of the cooked folder is 100MB but final APK is 160MB Although the APK is compressed?
And I’m surprised Although my project files(not engine content) in the cooked folder are just 50mb, why the final APK has so large size?

*Good to know that my build configuration is on shipping mode and does not include editor content in the build.
