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.

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 ?
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.....
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.
@@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?
For making fifteen cuts sir did 5+5+5 cuts =(6*6*6)=216 cuts. Can we also do this as (3+3+3+3+3)cuts giving (4*4*4*4*4) =1024 cuts. Will that be wrong. It would be very helpful if sir or any one of you can explain me this.
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.

How was your result in cat? How much percentile you got? please give any tip
In 1 Dimension, when we are cutting then if we cut across both diagonals and one in centre gives us 6 pieces.

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

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

With 6 cuts we can get maximum of 42 pieces (unidentical pieces).

Where n is number of cuts.

In the question pieces are not necessary to be identical is assumed.

How was your cat'24 result? Did you convert any iim?😂
Are there all the videos on youtube ? is there anything extra on unacademy apart from live classes?

Sir but isn't there any easy steps to convert pieces into cuts... Like 1001 ka pieces is 7×11×13 how can we derive that easily... Plz tell na
Those who didn't get for 294 pieces max. we can make 293 cut as ( pieces = Cut + 1 )

Sir when vedio comes in 23:30 min. There is 7*11*13 you write but they all are more than 1 difference. Thery are not closest number.

can we say pieces = (N+1) cuts?

sir but when we do 28 cuts ,via logic it should be 9+9+10=810
seems like 1001 is an exception.

For making fifteen cuts sir did 5+5+5 cuts =(6*6*6)=216 cuts. Can we also do this as (3+3+3+3+3)cuts giving (4*4*4*4*4) =1024 cuts. Will that be wrong. It would be very helpful if sir or any one of you can explain me this.
U can cut a cube in only 3 dimensions (5+5+5). For 3 cuts on each side there should be 5 dimensions which is impossible.
Great explanation
Please make more videos..
Suppose they give a random number and ask for the min cuts then how can I factorize that number?
my point exactly... he didnt tell the methodology
Then you can cut in 1-D right?
