Invisible cubes

I have placed in a cube but it was transparent,And I couldnt see it yes I pressed F to view to it and worked but when i did it just was invisible.Any ideas in making it so it isnt?

Make sure you have a Mesh Renderer on it.

Mesh Renderer

Are you looking from inside the cube to the outside? That won’t work… the normals point outwards

No I cant see the color…Like I have mesh render on it.
