The NCERT solutions for Class 8 maths Chapter 7 Cubes and Cube Roots explains the pattern of cubes which is when a number is multiplied by itself three times. Our whole cosmos is made up of different patterns, from the way the planets go around the sun to the number of petals we see in the flowers, to the pattern of the sea waves hitting the shore, based on different months or seasons of the year. 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. The Class 8 maths NCERT solutions Chapter 7 Cubes and Cube Roots helps students learn the calculation of cube roots and the interesting facts as well as patterns related to them and also you can find some of these in the exercises given below.
