In the BCC metal iron, the (110)-type planes are the most closely packed planes.

(a) Calculate the interplanar spacing between the (110)-type planes.
(b) Draw a BCC unit cell and show the (110)-type planes and a [110] direction that is perpendicular to the (110) planes.
(c) Calculate the segment lengths where the (110) planes cut the [110] direction.






(b) Draw a (110) and [110] in a cubic unit cell.
