Cube root table is a table consisting of a list of numbers and their cube roots. Before we write the cube root table, it is very important for all of us to understand what is the perfect cube root chart and cube of a number. The cube of any real number can be defined as that number which is obtained by multiplying a number by itself twice or by raising its power to 3. At the same time, the cube root of any number is that number which when raised to the power 3 gives the answer as the number whose cube root is to be determined.
Cube root of a number can also be exponentially represented as the number raised to the power ⅓. If ‘x’ is any real number, then its cube root is represented as (x)⅓ or ∛x. Perfect cubes are the numbers that are obtained when natural numbers are multiplied by itself twice. All the perfect cube numbers have a square root equal to a natural number. The perfect cube root chart of the first 25 perfect cube numbers is represented in the table below.
While it is very important to know the cube roots of the numbers, it is also very important to know the table of cubes from 1 to 50 (i.e. first 50 natural numbers) in order to make our Mathematical computations easy and efficient without a calculator. The table of cubes from 1 to 50 is given below for the reference of students and facilitators.
Any student or a facilitator who is keen about Mathematics will find his or her own ways to memorize the cube root list 1 to 100. Though it may seem little difficult at the initial days, the task of remembering the cube root list 1 to 100 becomes more and more easy through continuous practice and periodic revision.
Cube and cube roots are inverse mathematical operations.
The Cube of a cube root of a number or the cube root of a cube of a number is the number itself.
1. Where do we use Cubes and Cube Roots?
Answer: Cubes and cube roots are used in several Mathematical and Physical computations. It is quite often used to derive the solutions of cubic equations. To be more specific, the knowledge of cube roots can be used to determine the dimensions of three dimensional objects with specific value. Cubes and cube roots are also used in day to day calculations of Mathematics while learning the concepts such as exponents.
2. Why is it Important to know the Short Tricks of Finding Cubes and Cube Roots?
Answer: Cubes and cube roots are the most favorite topics of the paper setters who frame question papers for competitive examinations. It is highly difficult to crack these exams without the knowledge of short tricks to find cubes and cube roots because most of the questions in these exams are time bound and restricts the use of calculators. So, the continuous practice of a few short tricks and tips to remember the cubes and cube roots of at least few numbers may help a lot.
