it has cubic cleavage, means perfect in {100}, {010}, {001} planes.
All minerals have a crystal form, but not all have cleavage.
An infinite number of planes. Picture a line and now picture planes going in every direction through the line,
i think 4
dose it matter?

it a double chain silicate.... figure it out. Two I think.
Halite, which is the mineral form of sodium chloride (NaCl), has three perfect cleavages. These cleavages occur at right angles, reflecting its cubic crystal structure. As a result, halite commonly breaks into cube-shaped fragments.
Halite and Calcite. Halite has what is known as cubiccleavage, where there is cleavage in three directions at 90 degree angles. Calcite has what is known as rhombohedral cleavage, where there is cleavage in three directions but at 120 and 60 degree angles.
Many minerals have "cleavage" that causes them to split on flat cleavage planes. Such minerals include micas (muscovite, biotite. phlogopite), calcite, gypsum, and feldspars. Cleavage is the result of the minerals' crystal structure that has weaker chemical bonds aligned in planes.
cleavage....
Halite belongs to the mineral group halides.
It must have at least one.
Two directions of cleavage, at 90 degrees to each other.
A silicate sheet has one cleavage plane, which allows it to split easily along this flat surface. This cleavage plane is a result of the structure of silicon and oxygen atoms arranged in sheets within the mineral.
Calcite commonly exhibits three notable cleavage planes, which are oriented at approximately 75-degree angles to one another. This characteristic cleavage is a key feature that helps in identifying calcite among other minerals. Additionally, calcite can exhibit a rhombohedral crystal habit due to the arrangement of its atoms. Overall, its cleavage and crystal structure contribute to its unique optical properties.
halite has 6 sides
Crystals come in different shapes, determined by how the molecules of compounds from which they are made can be packed together. For instance a quarts crystal is hexagonal in shape, while galena and pyrites crystals are cubic. There are six different crystal shapes or forms determined by the axes and degree of symmetry of the crystal and the angles at which the axes intersect. Subordinate to the overall crystal shapes, many crystalline substances have within them planes of weakness along which the crystal may break these lines are related to the crystals symmetry and caused by how the molecules are aligned within the crystal. This is cleavage.
