The vacant space in close packed arrangement is called voids.

Tetrahedral void: A void surrounded by four spheres in tetrahedral position is called tetrahedral void. In a close packed arrangement the number of tetrahedral voids is double the number of spheres, i.e. there are two tetrahedral voids per sphere.
Octahedral voids: A void surrounded by six spheres in octahedral position is called octahedral void. In a close packed arrangement the number of octahedral voids is equal to the number of spheres, i.e. there is only one octahedral void per sphere.
If there are N close packed spheres, The number of tetrahedral voids = 2N and The number of octahedral voids = N.

Hope you are happy with the answer!
Thank you so much . Study well❤️❤️
