le cube

The French word "cube" refers to the same concept as in English: a three-dimensional geometric figure bounded by six square faces, with all sides of equal length.

Meaning:

1. Geometric shape: A cube is a solid figure with six equal square faces, twelve equal edges, and eight vertices. It is one of the basic shapes in geometry.
2. Mathematical operation: In mathematics, to "cube" (le cube) a number means to raise it to the power of three (e.g., ( 2^3 = 2 \times 2 \times 2 = 8 )). The verb form is "cuber" (less common in French).

Parts:

• The word is simple and does not break into smaller parts. It is borrowed directly from Latin cubus and from Greek κύβος (kúbos).

French synonyms:

• For the geometric shape, there isn't a true synonym because it's a specific shape, but you might say:
  • Parallélépipède carré (rectangular parallelepiped with square faces) – more technical and less common.

For the mathematical operation (to cube a number), there is no precise synonym; people usually say "élever au cube" (raise to the cube).

French antonyms:

There are no direct antonyms because this refers to a specific shape or operation. However, considering geometry, opposite or contrasting shapes could be considered:

• Sphère (sphere), a shape with curved surfaces and no edges.
• Cercle (circle), 2D shape, opposite to 3D cube.

Summary:

• cube (m.): a three-dimensional solid with six square faces.
• Used also as a mathematical term for the third power of a number.
• Related verb: cuber (to cube a number, rare).
• No direct synonyms or antonyms, but context-dependent.
