i think you glided over why cube roots are not constructible. you stated that the construction you showed can't do it, but that doesn't preclude other constructions. (I know there aren't, just saying you haven't said why.)

your comment is right. I glided. you have such a keen eye. I wanted to focus on the issue this video is dealing with. sorry and thanks😁
