How to Calculate Cubes 1 to 30?
The cubes from 1 to 30 can be calculated by using two methods, which are
- By Multiplying the Number Itself
- Using Algebraic Identities
By Multiplying the Number Itself
The cube of any number from 1 to 30 can be easily calculated by multiplying a number itself three times, i.e. the cube of 9 is calculated as,
93 = 9 × 9 × 9 = 81 × 9 =729
Thus, the cubes of all the numbers from 1 to 30 are calculated.
Using Algebraic Identities
The cube of any number from 1 to 30 can also be calculated by using algebraic identities as,
293 = (30-1)3
Using Algebraic Identity, (a – b)3 = a3 – b3 – 3ab(a – b)
293 = (30)3 – (1)3 – 3(30)(1)(30-1)
⇒ 293 = 27000 – 1 – 2610
⇒ 293 = 24389
Thus, the cubes of all the numbers from 1 to 30 are calculated.
Cubes 1 to 30
Cubes 1 to 30 are the cubes of the natural number from 1 to 30 and these cubes are very useful for solving various problems of mathematics. Learning these cubes from 1 to 30 is very useful for the students. The Cube of a number is found by multiplying the number by itself three times. Using the exponent’s formula x3 gives the cube of a number. Suppose we have to find a cube of 21 then,
213 = 21 × 21 × 21 = 9261
Similarly, the cube of all the numbers is found. In this article, we will learn about the cubes of numbers from 1 to 30, their charts, examples, and others in detail.
