I think he means how to get it out of wireframe as that's the mode it's in when you create a primitive, if that's the case, it's as simple as hitting 5 on your keyboard as Gster has said Kenitai, or in your view port, go to Shading> Smoothshade all, or for the flat surface and the wireframe shown, Shading>Wireframe on Shaded, hope that's helped, if that's not what you meant please explain further!
