The cube of 1 is 1, the lowest cube value for numbers 1 to 20 cube list.
The cubes of 10 and 20 are obtained by simply adding two zeros to the number.
The cube of all even numbers between 1 and 20 are even numbers.
The cube of all odd numbers between 1 and 20 are odd numbers.
When we divide the cube of a number by the number itself, the result is the perfect square of the number. For example, 8 ÷ 2 = 4 (since 2³ ÷ 2 = 2²).
Numbers ending with 0, 1, 4, 6, and 9 will have cube values ending with 0, 1, 4, 6, and 9.
Understanding these patterns helps you learn cube 1 to 20 better.
Example:
3 3 = 3 × 3 × 3 = 27 5 3 = 5 × 5 × 5=125Example:
( −3) 3 =(−3) × (−3) × (−3) = −27 (−5) 3 = (−5)×(−5)×(−5) = −125This rule also applies while calculating the cube 1 to 20 values for negative numbers.

Example :
Find the cube of 9 : 9 3 = (10 − 1) 3 Using the identity: (a − b) 3 = a 3 − b 3 − 3ab(a − b) Here, a = 10, and b = 1 9 3 = (10) 3 − (1) 3 −3(10)(1)(10−1) 9 3 = 1000 - 1 - 270 9 3 = 729 This method is especially helpful when working with numbers close to a base value, such as 10.Read More: Profit Formula

1. If the sides of a cubical water tank are 17 cm, find its volume.
Solution:
The formula for the volume of the cube is a 3 , where 'a' is the side of the cube. Here, a = 17 cm So, the volume of the cubical water tank is V = (17) 3 = 4913 cubic cm.2. Find the value of 3 times 8 cubes plus 5 times 14 cubes.
Solution: The expression will be: 3 x (8) 3 + 5 x (14) 3 = 3 x 512 + 5 x 2744 = 1536 + 13720 = 15256 So, the value of the expression is 15,256.3. Find the volume of a sphere having a radius of 18 cm.
Solution:
The volume of a sphere is 4/3 x π x r 3 , where r is the sphere's radius. Here, r = 18 cm. So, volume of sphere = 4/3 x π x (18) 3 = 4/3 x 3.14 x (18) 3 = 4/3 x 3.14 x 5832 = 4 x 3.14 x 1944 = 24416.64 cubic cm.4. Find the cube of 32 using the cube table from 1 to 20.
Solution:
We can write 32 = 20 + 12 So, (32) 3 = (20 + 12) 3 = (20) 3 + (12) 3 + 3 x 20 x 12 (20 + 12) = 8000 + 1728 + (720 x 32) = 8000 + 1728 + 20,040 = 32,768Related Articles | |
