    look at the structure of SC structure and BCC structure you will find an extra plane in bcc at 111 position while in sc structure it doesn't exist that's why 111 plane of bcc is just half distance of 111 plane of SC therefore divide by 2 the intrer-planer spacing of SC for Bcc . And 111 plane makes a equilateral triangle therefore it's are is √3/2 a^2. draw three dimensional Cartesian coordinate make a triangle using 111 at xyz Axis u will get same area
