Problem of not viewing the object properly

hi I m having a problem ,when I view my cube in Scene window or any other object in scene window I only saw the outlines of it there is no inner body shown to me.please answer my query if anyone knows it

Right under the Scene tab there’s a dropdown that has several options to control how things are displyaed. I would guess it’s set to Wireframe. Change it to Textured.

There’s another dropdown to the right of that. Make sure it’s set to RGB.
