When running ls -l, why does the file size in the directory not match the du output?

Question

What does 4096 mean at the output ls -l?

[root@file nutch-0.9]# du -csh resume.new/
2.3G    resume.new/
[root@file nutch-0.9]# ls -l 
total 55132
drwxr-xr-x  7 root root     4096 Jun 18 03:19 resume.new
