Amidst all these patterns we human beings have been trying to unravel the many mysteries of nature and predict how different events unfold and mathematics has been the language devised to depict these patterns.
The NCERT solutions Class 8 maths Chapter 7 show that whenever a number is multiplied by itself three times we get another number. What relations can be made with respect to the new number which we call the cube of the original number. Famous story for one such relation made by a famous Indian mathematician is his observation on Taxi number ‘1729’ which he remarked is the smallest number that can be expressed in two different ways as summation of cubes of two numbers.
