# Different Types Of Three Dimensional Shapes

254 Geometry is a branch of mathematics that deals with the varied shapes and sizes of distinct figures as well as their attributes. There are two forms of geometry: flat and solid geometry. Plane geometry is concerned with flat shapes that may be drawn on paper, such as lines, curves, and polygons. Solid geometry, on the other hand, deals with three-dimensional objects like cylinders, cubes, and spheres. The surface area of cylinder and other three-dimensional object’s surfaces is its surface area. Surface area is vital to understand in cases where we wish to wrap something, paint something, or build something to achieve the greatest potential design.

## Here are few fundamental elements of solid geometry or three-dimensional geometry

• Cube: The cube is one of the five Platonic solids and is the only regular hexahedron. It is made up of six faces, twelve edges, and eight vertices. A square parallelepiped, an equilateral cuboid, and a right rhombohedron are all examples of the cube. In three orientations, it’s a standard square prism, and in four, it’s a trigonal trapezohedron. The octahedron and the cube are twins. Its symmetry is cubical or octahedral. The only convex polyhedron with entirely square faces is the cube.
• Prism: A prism is a three-dimensional structure with two equal ends, flat surfaces or faces, and a cross-section that is the same all the way around. The prism is known as a triangular prism because its cross-section resembles a triangle. There is no curve in the prism. A prism also has six vertices, nine edges, and five faces – two triangles and three rectangles.
• Pyramid: Polygonal root to a point known as the pinnacle in geometry. A lateral face is a triangle formed by the base edge and zenith of each lateral face. All pyramids are dual in nature. A reel diagram is the backbone of a pyramid. The peak of a right pyramid is immediately above the base’s centroid. Oblique pyramids are non-right pyramids. The basis of a normal pyramid is a normal polygon, and it is commonly inferred to be a right pyramid.
• Sphere: A sphere is a solid defined in three-dimensional space that is perfectly spherical in shape. A sphere is defined mathematically as a group of  three-dimensional points that  are all at same distance from a central point. A sphere’s radius  is a constant distance, and the common point is the sphere’s centre. A ball is an example of a spherical in real life.
• Cone: A cone is a solid object that has a single vertex and has a circular base. From one circular flat base to the topmost point called the zenith, the figure cone can decline smoothly. One round flat face, one edge, one vertex, and one curved face are the properties that a cone can have.
• Cylinder: At an extent, a cylinder has two parallel circular bases. A curving surface connects the two circular bases at a predetermined extent from the centre. The axis of the cylinder is a line segment that connects the centres of two circular bases. The elevation of the cylinder equals the distance between the two circular bases. The cylinder has two major qualities, namely surface area and volume, because it is a three-dimensional shape. The cylinder’s total surface area parallels the sum of its curved surface area and the area of its two circular bases. The volume of cylinder is the three-dimensional space it occupies.
