cúbicos

Cúbicos is the plural form of cúbico, an adjective used in Spanish to indicate relation to a cube, to three-dimensional space, or to measurements expressed in cubic units. The term appears across mathematics, geometry, physics, and crystallography, among other fields, and can denote both shapes and quantities.

In geometry, a cube is a regular hexahedron with six equal square faces, twelve edges, and eight vertices. If the edge length is s, its volume is s^3 and its surface area is 6s^2. The adjective cúbico is commonly applied to lengths, areas, and volumes that are measured in three dimensions, such as centímetros cúbicos (cm^3) or metros cúbicos (m^3).

In mathematics, a número cúbico or cubical number is an integer equal to n^3 for some integer n (for example, 1, 8, 27, 64). In algebra, cubic equations have degree three and take the form ax^3+bx^2+cx+d=0, where a, b, c, and d are constants.

In crystallography and mineralogy, cúbico describes crystals with cubic symmetry, belonging to the systema cúbico. Crystals in this category often exhibit equal axes and a high degree of symmetry, as seen in many minerals with cubic lattices.

Overall, cúbicos refers to concepts that involve the cube or cubic measurements, as well as to related geometric, algebraic, and crystallographic contexts. Its usage emphasizes three-dimensionality and symmetry across disciplines.
