Need help using num2str?

I am trying to display the sentence:
The approximate work done is {W} kJ.
(Where W is the calculated work variable) How can I do this using just one line? I'm fairly certain I need to use the num2str command. Thanks in advance!
Right now this is what I have, but I want it to be all one line...
disp('The approximate work done is: ')
disp(W)
disp('kJ')

disp(['The approximate work done is: ',num2str(W),' kJ'])
The way I personally approach constructing things like this is to first write out the sentence without using the variable:
disp(['The approximate work done is: 123 kJ'])
then isolate the numeric piece, using concatenation:
disp(['The approximate work done is: ','123',' kJ'])
and then substitute in the num2str as above.
