Hello,

the number of tetrahedral voids are 8. Two tetrahedral voids are present on each body diagonal at a distance of 1/4th from every corner . The total number of tetrahedral voids is equal to the product of number of body diagonals (4) to number of tetrahedral voids in one body diagonal (2)

number of tetrahedral voids = 4*2 = 8

hope you understood this.
