Generally, awk works better than bash for something like this.

awk '{ foo += $1 } END { print foo }' report.txt

would print out the total (assuming report.txt contains everything in 
blocks, and not humanly readable sizes like it is now)

You could instead do something like

awk '{ foo += $1 } END { print foo/1024 }' report.txt

to convert it back to humanly readable....
