If you look to a simple tool for simple "drawing" -> LibreOffice Draw.
If you look for complex tool with parametric design (I change one dimension and everything is updated) -> FreeCAD.

To achieve this with LibreCAD needs drafting in a similar way as hand drafting:
1/ Draw a new box with the correct measurements
2/ Create the dimensions to show the measurements;
Video tutorial should be able to teach you this quite efficiently.

But I do not know any intuitive software so you probably want to try hand drafting (this is intuitive and fast at least for simple design).
