Explanation / Answer

For face x ,

Miller indices are 1/ 1.5 , 1/3 , 0

That is 2 , 1 ,0

If a face is parallel to a axis then it's corresponding Miller index is 0. as 1/infinity = 0 .

For face Y = Miller index = 1/ 1.6 , 1/0.8 , 1/-1.2

= 3, 6 , -4

For face z Miller index = 1/-4. , 1/2 , 1/12

That is -3, 6,1
