Heksaedri

Heksaedri, commonly known as cubes, are three-dimensional geometric shapes belonging to the family of polyhedra. They are a specific type of prismatoid and, more precisely, a regular hexahedron. A hexahedron is a polyhedron with six faces. In the case of a regular hexahedron, all six faces are congruent squares.

These squares meet at right angles at the edges. A heksaedri has 12 edges, and at each vertex, three faces and three edges meet. The word "heksaedri" itself is derived from Greek, with "hexa" meaning six and "hedra" meaning face or seat.

Heksaedri are fundamental shapes in geometry and have numerous applications. They are one of the five Platonic solids, which are convex polyhedra with congruent regular faces and congruent angles between faces. Their symmetrical properties make them useful in various fields, including architecture, crystallography, and in the design of dice for games. The volume of a heksaedri is calculated by cubing the length of one of its sides (side * side * side), and its surface area is six times the area of one of its square faces (6 * side * side).
