# THREE DIMENSIONAL FIGURE VOCABULARY

## About "Three dimensional figure vocabulary"

Three dimensional figure vocabulary :

Here we are going to learn what are three dimensional figures, its pictures and the formulas used in this topic.

An object with three dimensions (such as height, width and depth) like any object in the real world. Example: your body is three-dimensional. Also known as "3D".

Let us see the three dimensional figures one by one.

(1) Sphere :

What is sphere ?

A Sphere is a set of points in space that are the same distance from a given point.

Real life examples of sphere:

A very good example we can say for spherical shaped solid is globe. Ball is another good example for spherical shaped solid.

The size of this kind of solid is depending upon the length of the radius. If the the radius is more the size will be more. If the radius is less the size of the solid would be less.

(2) Cylinder :

What is cylinder ?

A cylinder is a solid with congruent parallel circular bases connected by a curved surface.

Real life examples of cylinder :

A soda can, a pencil shaft and a can of soup are the real life examples of the shape cylinder.

(3) Cone :

What is cone ?

A cone is a solid with circular base curved by a curved surface to a single vertex.

Real life examples of cone :

An ice cream cone, a pencil tip and a mega phone are the real life examples of the shape cone.

(4) Cube :

What is cube ?

A cube is a right rectangular prism with square upper and lower bases and a square vertical faces.

Real life examples of cube :

A sugar cube, ice cubes and dice are the real life examples of the shape cube.

(5) Cuboid

What is cuboid ?

cuboid is a three-dimensional shape with a length, width, and a height. The cuboid shape has six sides called faces

Real life examples of cuboid :

A pencil box, fish tank are the real life examples of the shape cuboid.

(6) Pyramid :

What is pyramid ?

A pyramid is a polyhedron that has polygon base and three or more triangular faces that meet at a common vertex.

After having gone through the stuff given above, we hope that the students would have understood "Three dimensional figure vocabulary".
