Cutting a cube & Identifying the cubic or cuboid after cutting it

Cutting a cube

It is a simple fact that if a wood or rod is to be cut in two equal parts, then we cut it one. Similarly, if the wood or rod is cut into three, four or five equal parts, then we cut it once, Or cut the bar n times, it cuts (N-1) times
top cube, middle cube, central cube,intermediate cube


If the cube with an 8 cm arm has to be cut into small cubes of 2 cm, then each surface will have 
N = (  8/2 )  = 4 sections and to divide it into four sections, the cube is divided from three sides to  ( N-1 ) = ( 4 -1) = 3 times, and after partition, = = 64 small cubes will be received


If a cube is to be cut into 8 small cubes, then the first cube root of 8 is called ∛8 =   = 2. In this case, we get 2 cubic roots, namely the cube from one on each side (n-1) On cutting, we will get 8 small cubes


Identifying the cubic or cuboid after cutting it


After cutting a small cubic material into a cub, a cube or cuboid is seen on the various parts of the cube or cuboid



Top cube - Such cube is located at the top of the corner ie every lane of its cube is equal to eight, because any cube has eight top or corners.


Middle cube - Such cube is located right in the middle of each edge



Central cube - Such cube is located at the right center of each surface


Intermediate cube - Such cube is located in the middle of the central cube of each surface, it is not visible from the outside, it is called the Kuclias cube.


The number of total small dances obtained after dividing the larger cube into smaller cubes =

Where    
                               

Number of top cube                    =             6 
Number of middle cube              =            12(n-2)
Number of central cube              =            
Number of intermediate cube    =             

Block counting


Such a three-dimensional shape whose length is equal to width and height, the shape is called cubic , such as ludo dice

Surface or Plane -

There is 6 surface in a sister or a cuboid which shows three surfaces and three does not appear


click here see video

Top (angle)

There are 8 corners in any cube or rectangle in which seven appear and one who does not appear

Corner-

In any cube or cuboid there are 12 edges in which 9 appear and three are not visible, which are hidden

Identifying the cubic or cuboid after cutting it

After cutting a small dense material into a dense lot, the dense on the different parts of it is identified as following.

Top cube 

Such cube is located at the top of each head, for each cube, its number is always 8, because someone's cube has 8 corners

Middle cube 

 Such cube is located in the right middle of each edge

Central cube

such a cube-such cube is located on the center cube of each surface

Inner central cube 

 Such cube-such cube is located on the right center of each surface from the cube
It does not appear blossom, it is called the nucleus cube

The small cube of the big cube will be the number of total small cubes obtained to split


The small cube of the big cube will be the number of total small cubes obtained to split
Where, one side of the big cube \ small arm of a cube

Top cube number  =   8

Number of mid cube = 12( n-2)

Number of Centers  =

Number of intermediates

figur count


Figure counting is a part of Non Verbal Reasoning, we will use easy method to solve figure counting.


So first of all, we teach about square counting. The class first asks for the column and cry of the square in the counting

After this, we do cry and column with the following formula.
                  














( r x c ) x ( r – 1 ) x ( c – 1 ) + (  r – 2 ) x ( c – 2 )………0


Count of rectangle and quadrilaterals



For counting rectangles and quadrilateral shapes, we will use a second formula, which is how we calculate rows and columns
First thing in the first formula















[( r ) + (r -1 ) + ( r-2) +(r-3) …..0] x [ ( c ) +(c-1)+(c-2)+(c-3)…..0]


This formula is used only for that rectangle and quadrilateral, whose shape is made of columns and birds, the quadrilateral divides into equal parts

Count of triangle

In the count of triangles, we start the first one and work the triangle equally, after which the cart number is added, this is the number of asking

Count of shells

We do not have any type of formula for counting of the balls, we normally do one by one, from small to large, which is stated in the video.
