Cone is cut from a cube, 
so height = radius=4 cm
formula to find slant height = sq.root of (h^2 + r^2)
                                             = sq.root of (16 + 16)
                                             = sq.root of 32
                                             = 4sq.root 2
                                             = 4*1.414
                                             = 5.656 cm

Hi @Oshoraa the answer is incorrect please have a look at it, the radius cant be 4 as it would be the diameter so please edit your answer and correct it
Slant height =2root10 = 6.32
