ike we did last week, add $1$ new $50$ MB Fixed Size Virtual Disk to your linux Partition. This is done using the Virtual Box interface while your Linux Virtual Machine is shut down.

Using fdisk create $3$ new $15$ MB $$linux$$ partitions on this newly added virtual disk.

Using mkfs$.$ext$4,$ create $3$ new filesystems on each new logical partition and mount them with the names below:

$/$math

$/$cs

$/$science

Once your filesystems are created and mounted, add an entry for each one in the $/$etc$/$fstab file in the corret format such that they automatically mount up when you reboot. Use UUID for the device so that the filesystem mounts even if the device address changes. Test and verify it is working by rebooting.
