Simple Shapes. Let us start with some of the simplest shapes: Common 3D Shapes. Properties. Solids have properties (special things about them), such as: volume (think of how much water it could hold) surface area (think of the area you would have to paint) how many vertices (corner points), faces and edges they have; Polyhedra and Non-Polyhedra

Asphereis a solid shape, absolutely round in shape, defined in three-dimensional space. Every point on the surface is equidistant from the center. The table below shows the properties of a sphere:
A cylinderis a solid shape defined on a three-dimensional plane. It holds two parallel bases, circular in shape, joined by a curved surface(like a tube), at a fixed distance. The table below shows the properties of a cylinder:
A cone is a distinctive solid shape defined in a three-dimensional space. It has a flat surface and a curved surface, pointing towards the top. It is formed by a set of line segments connected from the circular base to a common point, known as the apex orvertex. Based on how the apex is aligned to the center of the base, a right cone or an oblique ...
A pyramid is a solid shape or a polyhedron with a polygon base and all lateral faces are triangles. Pyramids are typically described by the shape of their bases. A pyramid with a: 1. Triangular base is called aTetrahedron. 2. A quadrilateral base is called a square pyramid. 3. Pentagon base is called a pentagonal pyramid. 4. Regular hexagon base is...
A prismis a solid shape defined on a 3-dimensional plane with two identical shapes facing each other. The different types of prisms are triangular prisms, square prisms, pentagonal prisms, hexagonal prisms, etc. Prisms are also broadly classified into regular prisms and oblique prisms. The table below shows the properties of a prism: (BA = base are...
Platonic solids have identical faces to regular polygons. There are five polyhedrons. 1. Tetrahedron with fourequilateral-triangular faces 2. Octahedron with eight equilateral-triangular faces 3. Dodecahedron with twelvepentagon faces 4. Icosahedron with twenty equilateral-triangular faces 5. Hexahedron or cube withsix square faces. The table below...
A face refers to any single flat surface of a solid object.Solid shapes can have more than one face.An edge is a line segment on the boundary joining one vertex (corner point) to another.They serve as the junction of two faces.A point where two or more lines meet is called a vertex.It is a corner.The point of intersection of edges denotes the vertices.Solid geometry or stereometry is the geometry of three-dimensional Euclidean space (3D space). [1] A solid figure is the region of 3D space bounded by a two-dimensional closed surface; for example, a solid ball consists of a sphere and its interior. Solid geometry deals with the measurements of volumes of various solids, including pyramids ...

The study of the properties, volume and surface area of three-dimensional shapes is called Solid Geometry. Let us go ahead and focus more on the study of geometrical solids.

These solid shapes occupy some space and are found in our day-to-day life. We can feel, touch, and use them. Definition of Solid Geometry: The study of 3-dimensional objects, their volume, surface area, properties is called the ‘solid geometry’. The geometrical figures are classified based on the dimensions as follows:
In simple words, they have volume. They have length, width, and height.The branch of geometry that deals with three-dimensional (3D) solid shapes is known as solid geometry. Common examples of solid geometric figures are cone, sphere, cube, cuboid. The geometric solid cube has three dimensions—length, width, and height.
