In geometry, threedimensional shapes or 3D shapes are solids that have three dimensions such as length, width and height. Whereas 2d shapes have only two dimensions,i.e. length and width. Examples of threedimensional objects can be seen in our daily life such as coneshaped ice cream, cubical box, a ball, etc. Students will come across these shapes in Class 6.
Geometry is one of the practical sections of Mathematics that involves various shapes and sizes of different figures and their properties. Geometry can be divided into two types: plane and solid geometry. Plane geometry deals with flat shapes like lines, curves, polygons, etc., that can be drawn on a piece of paper. On the other hand, solid geometry involves objects of threedimensional shapes such as cylinders, cubes, spheres, etc. Here we will discuss a few fundamental elements of solid geometry or threedimensional geometry.

What are ThreeDimensional Shapes?
Shapes that can be measured in 3 directions are called threedimensional shapes. These shapes are also called solids. Length, width, and height (or depth or thickness) are the three measurements of threedimensional shapes. These are the part of threedimensional geometry. They are different from 2D shapes because they have thickness. Several examples can be found in everyday life. Some of them are:
Solid Shapes in Maths
In Mathematics, the threedimensional objects having depth, width and height are called solid shapes. Let us consider a few shapes to learn about them. You can find many examples of solid shapes around you, such as a mobile, notebook or almost everything you can see around is a solid shape.

Faces, Edges, and Vertices of Three Dimensional Shapes
Threedimensional shapes have many attributes, such as vertices, faces, and edges. The flat surfaces of the 3D shapes are called faces. The line segment where two faces meet is called an edge. A vertex is a point where three edges meet.

List of Threedimensional Shapes
The list of 3d shapes are given below:
 Cube
 Cuboid
 Cylinder
 Cone
 Sphere
 Prism
 Pyramid
Here, we are going to discuss the list of different threedimensional shapes with their properties and the formulas of different 3D shapes.
Cube
A cube is a solid or threedimensional shape which has 6 square faces. The cube has the following properties.
 All edges are equal
 8 vertices
 12 edges
 6 faces
Cuboid
A cuboid also called a rectangular prism, where the faces of the cuboid are a rectangle in shape. All the angle measures 90 degrees. The cuboid has
 8 vertices
 12 edges
 6 faces
Prism
A prism is a 3D shape which consists of two equal ends, flat surfaces or faces, and also has identical crosssection across its length. Since the crosssection looks like a triangle, the prism is generally called a triangular prism. The prism does not have any curve. Also, a prism has
 6 vertices
 9 edges
 5 faces – 2 triangles and 3 rectangles
Pyramid
A pyramid a solid shape, whose outer faces are triangular and meet to a single point on the top. The pyramid base can be of any shape such as triangular, square, quadrilateral or in the shape of any polygon. The most commonly used type of a pyramid is the square pyramid, i.e., it has a square base and four triangular faces. Consider a square pyramid, it has
 5 vertices
 8 edges
 5 faces
Cylinder
A cylinder is defined as a threedimensional geometrical figure which has two circular bases connected by a curved surface. A cylinder has
 No vertex
 2 edges
 2 flat faces – circles
 1 curved face
Cone
A cone is a threedimensional object or solid, which has a circular base and has a single vertex. The cone is a geometrical figure that decreases smoothly from the circular flat base to the top point called the apex. A cone has
 1 vertex
 1 edge
 1 flat face – circle
 1 curved face
Sphere
A sphere is a threedimensional solid figure which is perfectly round in shapes and every point on its surface is equidistant from the point is called the center. The fixed distance from the center of the sphere is called a radius of the sphere. A sphere has
 No vertex
 No edges
 1 curved face
How to Make 3d Shapes for Maths Project
If you know what threedimensional shapes are, it would be easy for you to build a 3d shape project for a house or a building. This would be easy for the students to make as they can measure the rooms easily. Rest all they need is cardboard, glue, scissors and art supplies to make it look exactly like a mini house or building.
Surface Area and Volume of 3D shapes
The two distinct measures used for defining the 3D shapes are:
 Surface Area
 Volume
Surface Area is defined as the total area of the surface of the threedimensional object. It is denoted as “SA”. The surface area is measured in terms of square units. The three different classifications of surface area are defined below. They are:
 Curved Surface Area (CSA) is the area of all the curved regions
 Lateral Surface Area (LSA) is the area of all the curved regions and all the flat surfaces excluding base areas
 Total Surface Area (TSA) is the area of all the surfaces including the base of a 3D object
Volume is defined as the total space occupied by the threedimensional shape or solid object. The volume is denoted as “V”. It is measured in terms of cubic units.
Shapes  Surface Area  Volume 
Cube  The Surface Area of a Cube = 6a^{2 }square units  The volume of a Cube = a^{3 } cubic units 
Cuboid  The Surface Area of a Cuboid = 2(lb+bh+lh) Square units  The volume of a Cuboid = lbh Cubic units 
Cylinder  The Surface Area of a Cylinder = 2πr(h +r) Square units
The curved surface area of a cylinder = 2πrh 
The volume of a Cylinder = πr^{2} h Cubic units 
Cone  Surface Area of a Cone = πr(r +√(r^{2}+h^{2}) Square units
Curved surface area of a cone =πrl square units Slant height of a cone = l = √(r^{2}+h^{2}) units 
Volume of a Cone = ⅓ πr^{2}h Cubic units 
Cylinder  Surface Area of a Cylinder = 2πr(h +r) Square units
Curved surface area of a cylinder = 2πrh 
Volume of a Cylinder = πr^{2} h Cubic units 
Sphere  Curved Surface Area of a Sphere = 2πr² Square units
Total Surface Area of a Sphere = 4πr² Square units 
Volume of a Sphere = 4/3(πr^{3}) cubic units 
Pyramid  Surface Area of a Pyramid = (Base area) + (1/2) × (Perimeter) × (Slant height) Square units  Volume of a Pyramid = 1/3 × (Base Area) × height Cubic units
