I modified the virtual hdd and lv size but when I check with df -h its size is wrong.

Code: 
df -h

The output shows that you've extended all the filesystem underlying layers of LVM.

You have not addresses the filesystem itself. Depending on your file system type you need to:
EXT4: sudo resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv
XFS: sudo xfs_growfs /

To find out the filesystem type you can: blkid /dev/mapper/ubuntu--vg-ubuntu--lv
