Word to describe a 3 dimensional shape?

Answer 1

a Cube, Pyramid and Sphere are all 3D shapes.

This because they all have properties of 3 dimensions, IE Length, Width and Heigth.

A Square, Triangle and Circle is only 2 dimensional, IE Lengt and Width.

Answer 2

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.
