Cone
a triangular pyramid
A cone is a three-dimensional shape. It has a circular base and tapers smoothly to a point called the apex. This shape occupies space and has depth, height, and width, distinguishing it from two-dimensional shapes, which only have length and width.
An octagonal prism is a three-dimensional geometric shape with two parallel octagonal bases connected by rectangular lateral faces. It has a total of 10 faces (2 octagons and 8 rectangles), 24 edges, and 16 vertices. The height of the prism is the distance between the two octagonal bases, and its volume can be calculated using the formula ( V = \text{Base Area} \times \text{Height} ). The surface area is calculated by adding the areas of the two bases and the lateral faces.
When describing three-dimensional shapes, we can use a variety of words and terms, which are often based on the shape's properties, dimensions, symmetries, surface properties, and relationship to other shapes. Here are some common words to describe three-dimensional shapes: geometry : This is a broad term used to describe any object that has a three-dimensional spatial shape. polyhedron : a three-dimensional shape consisting of multiple planar polygonal faces, such as a cube, tetrahedron (pyramid), octahedron, etc. sphere : a three-dimensional shape with all points equidistant from the center of the sphere and perfect symmetry. cylinder : A three-dimensional shape formed by a rectangular or circular base rotated once along one side, having two parallel circular bases. cone : A three-dimensional shape formed by connecting a circular base and a vertex (not on the base) by straight lines (bus bars). The distance from the base to the vertex is called the height. prism : a three-dimensional shape with a polygon on the bottom and a rectangle or parallelogram on the sides, such as a cuboid or triangular prism. pyramid : a three-dimensional shape with a polygon on the base, the vertices not on the base, and a triangle on the sides, such as a tetrahedron (triangular pyramid). surface : a three-dimensional shape, such as a sphere, cylinder, or cone, with a surface rather than a planar polygon. symmetry : describes the properties of three-dimensional shapes that remain constant under operations such as rotation, reflection, or translation, such as a sphere having perfect symmetry in all directions. volume : The size of the space occupied by a three-dimensional shape, usually measured in cubic units, such as cubic meters. surface area : The sum of all outer surface areas of a three-dimensional shape, used to describe the shape's outer covering area. edge : a line segment connecting two vertices, especially in polyhedra. vertex : the intersection of three or more edges in a three-dimensional shape. surface : a two-dimensional area enclosed by an edge in a three-dimensional shape. It can be a plane or a surface. Irregular shape : a three-dimensional shape that cannot be accurately described by simple geometry or regular combinations. These words and terms provide a rich linguistic tool for describing and understanding three-dimensional shapes.

A 3-D octagon is called an octagonal prism. It is a geometric figure with two parallel and congruent octagonal faces connected by rectangular faces. The octagonal prism has 10 faces, 24 edges, and 16 vertices.
