New cube linked to the old object, how to make them separate? I am just starting out with blender and I don't know why the new cube that was added to the scene is tied to the old cube object.
Below image will explain

When I am selecting either of them, both get selected.
Please help me in deleting only the new cube. And please explain why it happened?
It looks like you added the little cube while you were in &quot;Edit&quot; mode, so it became part of the same mesh as the chair. You will need to go back into &quot;Edit&quot; mode, select all the faces of the little cube and delete them.

&quot;tab&quot; for edit mode
&quot;alt&quot;-a deselect all
&quot;3&quot; for face mode
select click a face on the little cube
&quot;Ctrl&quot;+l for all linked faces
&quot;p&quot; to separate to new item
