sir how would we know that we have to start from minimum side and how much of that quantity should be cut
sir plz make a video on this
this is new approach
requsted sir
Amazing approach
Sir eska koi formula nahi hai kya
70
20×50 equals 1000 so its perfect cube and every cube vol must have perfect cube and it also multiply by 70 so minimum 70 is possible if we take less side then many more are possible
Sir agar hum figure ko 70 identical cubes me divide kare. To 64 identical cubes ko mila kar hum ek bada cube bana sakte hai…. Aur baki bache hue 6 cubes jo 10*10*10 ke hai wo as its rahenge. To minimum 7 bhi to ho sakte hai.
