    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.

      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

      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.

    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?
