Is the shape of a tetrahedral void tetrahedral? If not, why is it so called?

Sketch a tetrahedral void.

Write a note on tetrahedral void.

Explain tetrahedral void.

Assertion: In a close packing of spheres, a tetrahedral void is surrounded by four spheres whereas an octahedral void is surrounded by six spheres. Reason: A tetrahedral void has a tetrahedral shape while an octahedral void has an octahedral shape

(A): A void surrounded by a triangle of spheres capped by another sphere is called tetrahedral void. (R) : Tetrahedral voids are in tetrahedral arrangement

(A) In close packing of spheres a tetrahedral void is surrounded by four spheres whereas an octahedral void is surrounded by six spheres. (R) A tetrahedral void has a tetrahedral shape whereas an octahedral void has an octa-hedral shape.
