I have a cube defined as :

  float vertices[] = {
            //Vertices according to faces
                -1.0f, -1.0f, 1.0f, //Vertex 0
                1.0f, -1.0f, 1.0f,  //v1
                -1.0f, 1.0f, 1.0f,  //v2
                1.0f, 1.0f, 1.0f,   //v3

                1.0f, -1.0f, 1.0f,  //...
                1.0f, -1.0f, -1.0f,         
                1.0f, 1.0f, 1.0f,
                1.0f, 1.0f, -1.0f,

                1.0f, -1.0f, -1.0f,
                -1.0f, -1.0f, -1.0f,            
                1.0f, 1.0f, -1.0f,
                -1.0f, 1.0f, -1.0f,

                -1.0f, -1.0f, -1.0f,
                -1.0f, -1.0f, 1.0f,         
                -1.0f, 1.0f, -1.0f,
                -1.0f, 1.0f, 1.0f,

                -1.0f, -1.0f, -1.0f,
                1.0f, -1.0f, -1.0f,         
                -1.0f, -1.0f, 1.0f,
                1.0f, -1.0f, 1.0f,

                -1.0f, 1.0f, 1.0f,
                1.0f, 1.0f, 1.0f,           
                -1.0f, 1.0f, -1.0f,
                1.0f, 1.0f, -1.0f,
                                    };

What are the normals for this cube? I need the actual values for the normals.

Do we need 6 or 12 normals? Since OpenGL ES uses only triangles which means we need 12 normals but I could be wrong.
