Answer 1

You didn't name the device, but that's the usual way manufacturers fool their customers without lying: the storage chip has 8GB, but guess where the OS is installed? Looks like on your device, ~4GB are reserved for this (/system). Then there are other partitions on the very same storage chip, e.g. for /recovery and /cache. What's left in the end is /data – storage space available for apps etc. Those are your 3.65GB.

RAM doesn't play a role in this context, it usually goes to a different chip.

For additional details, please take a look at my answer on Android Folder Hierarchy.

Using a Terminal App, you can see the storage details using comman-line tools:

• df (short for "disk free") shows you all mounted partitions together with their sizes (and some more details) in an easy-to-read style
• details about all partitions are held in /proc/partitions, which you could display using e.g. cat /proc/partitions. While being more complete, this is harder to read.

Both commands will display your storage and show where the missing ~4GB have gone to. While df is not that complete, you will hardly notice the "missing parts", as those are usually very small partitions (like /boot and /recovery).
