Cube Of A Number All Math Tricks Here we take 72 – 8 . step 2 : divide the 1st part by 2nd part. i.e 72 8 = 9. here we can take a = 8 , b= 9 , c = 8³ = 512. step 3 : cube of 1st part c = 8 x 8 x 8 = 512. here take last digit in answer and remaining value 51 to be add to next step. i.e ans : 2 and 51 is to be add in the next step. We all know, to solve the cube of a number, we use the formula (a b) 3 which is a 3 3a 2 b 3ab 2 b 3. now, we will be using this method only but in a smart way so that you can find out the cube in cubes can be solved in exams in just a few seconds and without writing all the steps. so, you have to do the complete calculation in a single go.
Cube Numbers 1 To 20 In this maths lesson we will learn how to find the cube of a number quickly and what cubing a number actually means! working with powers is an essential skil. Hello friends, in this video, we are going to give a simple trick to find a cube of any number in just less than 60 sec, which is useful to you in your exams. Hey! in this video, we are going to give you a trick which will reduce the probability of a mistake in exams as well as consumes less time in respect to the. Step 1: write numbers in a row of 4 terms in such a way that the first one is the cube of the 1st digit, second one is the square of 1st number multiplied by 2nd digit, third one is the 1st digit multiplied by square of 2nd digit and the fourth one is the cube of the 2nd digit. step 2: write twice the values of 2nd and 3rd terms under the terms.

It is easy to work out the cube root of a perfect cube, but it is really hard to work out other cube roots. example: what is the cube root of 30? well, 3 × 3 × 3 = 27 and 4 × 4 × 4 = 64, so we can guess the answer is between 3 and 4. To find the cube of fraction, we have to find the cube of numerator and denominator separately. otherwise, we may multiply the fraction three times itself. example 2 : find the cube of the fraction 3 4. solution : (3 4)3 = (3 4) ⋅ (3 4) ⋅ (3 4) product of numerators = 27. product of denominators = 64.
