Changing dimensions without changing the scale

On the side panel I typed the dimensions I wanted for a cube but the scale changed as well. Then when I grabbed the individual faces of the cube & manually manipulated them the dimension changed but the scale stayed the same.

So, my question is "Is there a way to type in the dimensions that I want without changing the scale?

I tried pressing the button with the lock on it in the scale section but that didn’t work either. Any help would be appreciated.

At any time apply the object scale with Ctrl+A

You can also make your changes to the scale in edit mode. This won’t change the object scale. But applying scale is just as easy. If your object is not a perfectly symmetrical one, you might have to adjust the object origin to make animation easier later though.

Thanks a lot Richard.
