Another way for the 1001 pieces problem could be that we approximate 1001 as 1000 and assume it to be 10*10*10 by that logic a number greater that 27 cuts and 28 cuts is the closest.

1001 is of form 6k-1, so to confirm if its not prime, take sqrt(1001), approx 30, try dividing 1001 with prime numbers below 30, 1,3,5,7: 7 you will get one, then try to factorise, you will get 143=11*13. keep doing small exercises while solving question, this is the beauty of maths.
Sir I didn't get the concept of 'minimum number of cuts required' from the given pieces coz I started my class from LR and DI section.can u please explain its concept in the comment section ?
With 6 cuts we can get maximum of 42 pieces (unidentical pieces). The formula is( n^3+5n+6)/6 Where n is number of cuts. What is the answer if 4 number of cuts are given according to it it's 15 but in practical you can get only 14 maximum cuts. How is this possible? The formula given by chatgpt is incorrect or there is something wrong here please help sir. In the question pieces are not necessary to be identical is assumed.
Sir at 18:15 ..32cuts why didn't we do 8+8+8+8=32 9×9×9×9=6561 max pieces Sir is this wrong Or right? Nd why we didn't do it like this? Any1 can answer 🙏
Kyonki hum maximum 3 different sides se hi cut kar sakten hain...upar se neeche( verticle) left to right or we can say right to left and last horizontal ( from mid of height )( starting me jab cube ke cuts show kar rahe the dekh lo ) isliye Hume 3 factors chahiye. For example 554 hai to 5 cuts one side and 5 cuts another and 4 cuts third side.....
@@utsachatterjee no we ain't taking closest numbers to each other. Emphasise on the point that we need to make maximum number of pieces from a given number of cuts. And thus, 2+2+2 will give 27 pieces. Otherwise, it can be cut in various ways. Hope you got the point .
27 identical cubes are arranged to form a large cube. How many such cubes are required to completely cover the large cube so that the figure obtained is also a cube? Can anybody please solve this question? The answer to this is 98. But what is the method?
Came here in full faith that he can make students understand the most feared topics, proved me right, as always.
It's the same for cuboid. The no. of pieces is same but size is proportional to original cuboid.

In 1 Dimension, when we are cutting then if we cut across both diagonals and one in centre gives us 6 pieces.
woah !!! What a explaination!! Thank you so much sir for your efforts.
I literally started my prep 1-2 weeks back and am following all your videos so closely and its been a boon

Thanks😂❤
Same for 504 pieces?
As 8×8×8=512 ; 21 cuts
And 8×8×7=488 comes out 20 cuts
So adding one more cut we can approximate 21 cuts

How one can factorise easily?
You made very easy to understand the cubes❤
While taking 6 cuts, we could have taken cuts in 6 different directions then it will be 2^6
but there are only 3 dimensions.
My doubt is each 1 in x,y,z and each 1 in mid of x-y,y-z,z-x .. as in along the diagonal

Agreed Bhagyashree! Thanks
the best teacher for cat.
if we cut x in one D , then x+1 pieces , to optimise we do x/3 cuts each in all dimensions and get (x/3+1)(x/3+1)(x/3+1) pieces
16:39 always take the closest
You are great

Those who didn't get for 294 pieces max. we can make 293 cut as ( pieces = Cut + 1 )
With 6 cuts we can get maximum of 42 pieces (unidentical pieces).
The formula is( n^3+5n+6)/6
Where n is number of cuts.
What is the answer if 4 number of cuts are given according to it it's 15 but in practical you can get only 14 maximum cuts. How is this possible?
The formula given by chatgpt is incorrect or there is something wrong here please help sir.
In the question pieces are not necessary to be identical is assumed.

Did RODHA take any online exam for cat preparation????? plzzzz ans my question !!!!
Yes, Ravi sir takes classes on unacademy plus. You can study there😊
I m not getting a thing.....why are we multiplying in case of pieces
sir but when we do 28 cuts ,via logic it should be 9+9+10=810
seems like 1001 is an exception.
When we make 28 cuts as 9+9+10 the maximum pieces we will get is 10×10×11 =1100 in the question sir did not mention maximum pieces
