Find the distance ( in pm) between the body centered atoms one corner atom in an element `( a = 2.32 "pm")`

Find the distance ( in pm) between the body centered atoms and one corner atom in an element ( a = 2.32 "pm")

The distance between the body centred atom and a corner atom in sodium (a = 4.225 Å) is

It a is the length of the side of a cube, the distance between the body centred atom and one corner atome in the cube will be :

If a is the length of the side of a cube, the distance between the body centred atom and one corner atom in the cube will be

If the edge length of the side of a cube is a, the distance between the body centred atom and one corner atom in the cube will be:
