Probably lots of better ways to do it, but this should work. Try this and 
edit to taste. :)

#!/bin/sh
device="/dev/hda"
cylinders=\
`fdisk -l $device | grep Disk | cut -d "," -f 3 | cut -d " " -f 2`
size=\
`fdisk -l $device | grep Units | cut -d "*" -f 1 | cut -d " " -f 5`
bytes=\
`fdisk -l $device | grep Units | cut -d "*" -f 2 | cut -d " " -f 2`
let TOTAL="$cylinders"*"$size"*"$bytes"
echo $TOTAL
exit
