    Fascinated to see such brilliant level of teaching with quintessential concepts and applications being available here for free. I have completed the entire geometry part this channel and could not have found a better channel/book/source for such wonderful depths of teaching. Sir Ravi Prakash is undoubtedly one of the best online tutors I've witnessed so far. Absolutely sine qua non for people who are preparing with no additional coaching or support. This one channel is perhaps more than enough to cover the entire syllabus and concepts of CAT exam(Quant is the best). Special thanks to Ravi Prakash Sir for imparting the knowledge and effort. 🙂👍🏻

  • @shashagaming4076

    Sir, i think it should be [underroot {(h+b)^2 + l^2}] and the cube should be opened vertically not sideways.

    • @shashagaming4076
      @shashagaming4076 2 года назад

      It actually doesn't matter in cuboid coz we are making it travel across any 2 corners with smallest distance between them. But still 😅

    • @ShivashishSharma-mp3gb
      @ShivashishSharma-mp3gb 11 месяцев назад +2

      Yes you are correct I am also having the same point and I think sir made that mistake which he usually never do and it was unnoticed by most of the people but you found it. And it does matters in the case of cuboid because the face along which we are moving decides what is the horizontal distance covered and vertically distance covered.

    Sorry sir .but .. Am having a big doubt.... Earlier in this lecture u said that it is ant, not sparrow can fly in air..... So how it is travelling from A to D in air 😕😕😕😕..... Also...contradiction here is that that This shortest distance we got root under l2 +b2+2lb+h2 is greater than the diagonal length of cuboid that u have taught earlier i.e root under l2+b2+h2 ...... Koi agree kr rha hai kya hmse😢😢😢

If anyone disagrees with me then draw the top layer and the front layer (layer over which ant crawls) in 2D as if opening the whole cuboid, you will find the right angled triangle we obtain is (b+h) as height of the triangle and (l) being the base of the triangle, now apply pythogoras theorem.

    Ant can also follow the path ACB, they can go to C point and then jump from it. It will be fastest way as well and save time of walking. Ant can fall from 1000 time higher then their height without getting hurt.
