Question

question 26 (2 points) which packing has an a - b - c repetition of hexagonal planes? hexagonal closest packing cubic closest packing simple cubic packing triclinic lattices octagonal meat packing

Explanation:

Hexagonal closest - packing has an a - b - c repetition of hexagonal planes. In cubic closest - packing, the repetition is of square - like planes. Simple cubic packing, triclinic lattices, and octagonal meat packing (which is not a valid packing in this context) do not have the a - b - c repetition of hexagonal planes.

Answer:

hexagonal closest packing
