 One of the methods of finding cubes in Vedic math is known as Yafdunam. Let's see. What is this method? So, let's say we wanted to find out the cube of 13 so what we need to do first is to find a base and we will call it B and We'll call the actual number this one as a and After finding the base, we will find a deviation Deviation is basically Actual number a minus the base and we will call it D Now what this base is a power of 10 that is closest to this given actual number and we have done this exercise in Earlier Vedic videos as well. So base in this case is going to be 10 actual number is 13 and the base is 10 So the deviation is going to be 3 now when we perform the cube of 13 There are three parts of the answer and I'm going to separate those parts with Two slashes the right most part of the answer is obtained by cubing the deviation So basically we we just put the cube of D here The left most part of the answer is given by a plus 2d So basically adding the deviation two times in the actual number The middle part is given by a plus 2d Minus B and this whole thing multiplied by D now remember because our base is 10 It has only one zero and that's why The right most and the central part will only have one place and if there is any carry that gets generated It will flow towards left. So now let us compute each and every part the right most part is the cube of three Which is going to be 27 The left most part is a plus 2d. So a is 13 then two times D. D is 3 So this is going to be 13 plus 6 which is 19 That's our left most part and let's find the middle part now. We already have found a plus 2d. So keep it Let's keep it there 19 minus B B is 10 and this this whole thing multiplied by Deviation, which is 3 so this is 9 times 3 which is 27. Let me just write 27 here and I have already mentioned that the right most part is only going to have one place So the two from here will flow as a carry to the towards left and that happens is On the right hand side instead of 27, we will have only seven and here we will have 27 plus 2 which is 29 this middle part as well now Generates a carry because this middle part only is reserved for one place so the two flows towards left as a carry and Instead of 29 in the middle We only have nine in the middle and 19 plus 2 is the left most part So we get 21 on the left most part and therefore the cube of 13 is 2197
