Suorakulmioksi

Suorakulmioksi, known in English as a rectangular pyramid or right rectangular pyramid, is a three-dimensional geometric figure characterized by a rectangular base and four triangular faces that meet at a common apex. The base of a suorakulmioksi is a rectangle, and the four triangular faces are congruent isosceles triangles (except in the case where the pyramid is a right rectangular pyramid, where the apex is directly above the center of the base).

The properties of a suorakulmioksi include its height, which is the perpendicular distance from the apex to the plane of the rectangular base, and its slant heights, which are the edges connecting the apex to the vertices of the base. The surface area of a suorakulmioksi can be calculated as the sum of the area of the rectangular base and the areas of the four triangular faces. Its volume is given by the formula V = (length × width × height) / 3.

Suorakulmioksi objects are commonly encountered in architecture and design, where rectangular pyramids are used as decorative elements or structural components. They are also studied in geometry education as an example of polyhedra and as a basis for understanding more complex pyramidal structures.

The concept of a suorakulmioksi is part of the broader family of pyramids in geometry, which includes various different base shapes such as triangles (tetrahedrons), squares, and other polygons. Its symmetrical properties and straightforward calculations make it a fundamental shape for both theoretical and practical applications in mathematics and engineering.
