In geometry, three-dimensional 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 three-dimensional objects can be seen in our daily life such as cone-shaped ice cream, cubical box, a ball, etc. Students will come across different 3D shapes models in Maths. Show
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 three-dimensional shapes such as cylinders, cubes, spheres, etc. In this article, we are going to learn different 3D shapes models in Maths such as cube, cuboid, cylinder, sphere and so on along with its definitions, properties, formulas and examples in detail.

Shapes that can be measured in 3 directions are called three-dimensional shapes. These shapes are also called solids. Length, width, and height (or depth or thickness) are the three measurements of three-dimensional shapes. These are the part of three-dimensional 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 MathsIn Mathematics, the three-dimensional 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 ShapesThree-dimensional 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. Also, read: Vertices, Edges and Faces Faces, Edges and Vertices List of Three-dimensional ShapesThe list of three-dimensional shapes are as follows: Three-dimensional Shapes Names:
Here, we are going to discuss the list of different three-dimensional shapes with their properties and the formulas of different 3D shapes. CubeA cube is a solid or three-dimensional shape which has 6 square faces. The cube has the following properties.
CuboidA cuboid is also called a rectangular prism, where the faces of the cuboid are a rectangle in shape. All the angles measure 90 degrees. The cuboid has
PrismA prism is a 3D shape which consists of two equal ends, flat surfaces or faces, and also has identical cross-section across its length. Since the cross-section looks like a triangle, the prism is generally called a triangular prism. The prism does not have any curve. Also, a prism has
PyramidA 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
CylinderA cylinder is defined as a three-dimensional geometrical figure which has two circular bases connected by a curved surface. A cylinder has
ConeA cone is a three-dimensional 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
SphereA sphere is a three-dimensional 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

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 shapesThe two distinct measures used for defining the 3D shapes are:
Surface Area is defined as the total area of the surface of the three-dimensional 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:
Volume is defined as the total space occupied by the three-dimensional shape or solid object. The volume is denoted as “V”. It is measured in terms of cubic units.

Solution: Given: Side length, a = 6 cm. We know that the volume of cube = a3 cubic units. Hence, V = 63 = 216 cm3 Hence, the volume of a cube is 216 cm3. Example 2: Find the total surface area of a sphere, whose radius is 3 cm. Use (π = 3.14) Solution: Given: Radius, r = 3 cm. The formula to calculate the total surface area of a sphere is given by: TSA of Sphere = 4πr² Square units TSA of sphere = 4(3.14)(3)2 cm2 TSA of Sphere = 113.04 cm2. Hence, the total surface area of a sphere is 113.04 cm2. Example 3: Find the volume of a cuboid, whose dimensions is 4cm × 6 cm × 12 cm. Solution: Given cuboid dimensions = 4cm × 6 cm × 12 cm We know that the volume of a cuboid is lbh cubic units. Hence, Volume of cuboid = (4)(6)(12) cm3. V = 288 cm3 Therefore, the volume of the cuboid is 288

Frequently Asked Questions on Three Dimensional ShapesThe three-dimensional shape in geometry are those shapes that are defined along three dimensions such as length, width and height. The different types of three dimensional
shapes are cone, cylinder, cuboid, cube, sphere, rectangular prism, pyramid. Square is not a three dimensional shape, instead it is a two dimensional shape. A three dimensional round shape is a sphere. For example, a football is a spherical shaped object. There are a number of examples of three dimensional shapes that can be seen in real life such as Rubik cube, a globe, gas cylinder, a cubical box, a cuboidal board etc. What are the kind of lines that establish the outside borders of a threecontours are the boundaries we perceive of three-dimensional forms and contour lines are the lines we draw to record those boundaries. A shape is a two-dimensional form, it occupies an area with identifiable boundaries. A mass is a three-dimensional form that occupies a volume of space.
What follows the outer edges of a shape?A contour is the line which defines a form or edge - an outline. Contour drawing is the place where most beginners start, following the visible edges of a shape. The contour describes the outermost edges of a form, as well as dramatic changes of plane within the form.
What form exists in three- Three-Dimensional is defined as: Space that has length, width, and depth. - Three-dimensional realm includes solidity, volume and mass. We associate it with objects that take up space such as a sphere, cube, or pyramid; or a tree, chair, or person.
What refers to the area around a shape or form?space. The element of art that refers to the emptiness or area between, around, above, below, or within objects. Shapes and forms are defined by space around, and with-in them. positive space (figures)

Form the outside edge of a three-dimensional shape and clearly defines the area it occupies.
