FAQs on Worksheet: Cubes and Cube Roots - Improve Your Calculations: Vedic Maths (English) - Class 6

1. What is a cube in mathematics?
Ans. A cube in mathematics refers to a three-dimensional geometric shape with six equal square faces. It can also refer to the result of raising a number to the third power, which means multiplying that number by itself twice. For example, \(3^3 = 3 \times 3 \times 3 = 27\).
2. How do you find the cube of a number?
Ans. To find the cube of a number, you multiply the number by itself twice. For instance, to find the cube of 4, you calculate \(4^3 = 4 \times 4 \times 4 = 64\).
3. What is a cube root, and how is it calculated?
Ans. A cube root is a value that, when multiplied by itself three times, gives the original number. It is denoted by the radical symbol \( \sqrt[3]{x} \). For example, the cube root of 27 is 3 because \(3^3 = 27\).
4. Can all numbers have cube roots, and are they always rational?
Ans. Yes, all real numbers have cube roots. However, while perfect cubes (like 8 or 27) have rational cube roots (2 and 3, respectively), non-perfect cubes (like 2 or 10) will have irrational cube roots.
5. What is the difference between a perfect cube and a non-perfect cube?
Ans. A perfect cube is a number that can be expressed as the cube of an integer, such as 1, 8, or 27. In contrast, a non-perfect cube cannot be expressed in this way; for example, 2 and 10 are non-perfect cubes because their cube roots are not whole numbers.
