A Square and A Cube
Square tiles on a floor and cubic boxes in a godown hide a pattern worth studying. Chapters 5 and 6, Squares and Square Roots and Cubes and Cube Roots, of the NCERT Mathematics textbook for Class 8 explore perfect squares and cubes, their properties and their patterns. You will find square roots by prime factorisation and by division, estimate roots that are not exact, and compute cube roots of perfect cubes. Patterns in unit digits and in sums of odd numbers make the search for roots quicker and more certain.
