How many octahedral & tetrahedral voids are per sphere in a unit cell ?

How many octahedral & tetrahedral voids are per sphere in a unit cell ?

Assertion:A tetrahedral void is surrounded by four spheres and an octahedral void is surrounded by six spheres. Reason:The number of tetrahedral voids is double the number of close packed spheres and number of octahedral voids is equal to number of close packed spheres.

Assertion:A tetrahedral void is surrounded by four spheres and an octahedral void is surrounded by six spheres. Reason:The number of tetrahedral voids is double the number of close packed spheres and number of octahedral voids is equal to number of close packed spheres.

Assertion:A tetrahedral void is surrounded by four spheres and an octahedral void is surrounded by six spheres. Reason:The number of tetrahedral voids is double the number of close packed spheres and number of octahedral voids is equal to number of close packed spheres.

Assertion : A tetrahedral void is surrounded by four spheres and an octahedral void is surrounded by six spheres. Reason : In hcp or ccp the number of tetrahedral voids is double the number of close packed spheres and number of octahedral voids is equal to number of close packed spheres.
