FAQs on Cubes & Cubes Roots - 2 Video Lecture - Class 8
| 1. What is a cube? |  |
Ans. A cube is a three-dimensional shape with six equal square faces. All the edges of a cube are of the same length, and all the angles are right angles.
| 2. What is a cube root? | |
Ans. A cube root is the number that, when multiplied by itself twice, gives the original number. For example, the cube root of 8 is 2, as 2 x 2 x 2 equals 8.
| 3. How can I calculate the volume of a cube? | |
Ans. The volume of a cube can be calculated by multiplying the length of one side of the cube by itself twice. So, the formula for calculating the volume of a cube is V = side length x side length x side length.
| 4. What is the relationship between cubes and cube roots? | |
Ans. Cubes and cube roots are inverse operations of each other. If we have a number and we cube it, we can find its cube root to get back the original number. Similarly, if we have the cube root of a number, we can cube it to find the original number.
| 5. How can I find the cube root of a number? | |
Ans. To find the cube root of a number, you can use a calculator or estimate it by trial and error. However, if you want to find the exact cube root without a calculator, you can use the prime factorization method or the long division method. Both methods involve breaking down the number into its prime factors and finding the cube root from there.
