What is the total size of your Linux installation and total partitions on the system?

I am going through the Linux documentation and trying to answer the following questions

1. On which partition is your home directory?
2. How many partitions are on your system?
3. What is the total size of your Linux installation?

I used the following commands to answer 1 & 2 but how to answer 3?

$ df -h Filesystem Size Used Avail Use% Mounted on udev 1.9G 0 1.9G 0% /dev tmpfs 385M 1.7M 384M 1% /run /dev/sda2 916G 9.0G 860G 2% / tmpfs 1.9G 8.0K 1.9G 1% /dev/shm tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs 1.9G 0 1.9G 0% /sys/fs/cgroup /dev/sda1 511M 6.1M 505M 2% /boot/efi tmpfs 385M 128K 385M 1% /run/user/1000 $ df -h /home/rishik Filesystem Size Used Avail Use% Mounted on /dev/sda2 916G 9.0G 860G 2% / $ df -h | wc -l 9

You have two real disk partitions, sda1 and sda2. Since sda1 is 511MB and sda2 is 916GB, your total size is roughly 917GB.
