Perfect Cubes Formula
The formula for calculating a perfect cube is:
Perfect Cube = n3
where n is Integer
For instance, if n=5, then 53= 125, making 125 a perfect cube.
Formula for factoring perfect cubes is:
a3 + b3= (a + b) × (a2 − ab + b2)
This formula is an expansion of the sum of cubes. For instance, consider 83 + 273 :
83 + 273= (8 + 27) × (82 − 8 × 27 + 272)
Solving this equation would give the factors of the sum of the cubes of 8 and 27.
Perfect Cubes – Definition, List, Chart and Examples
Perfect cubes are numbers that result from multiplying an integer by itself twice. A number is said to be a perfect cube if it can be decomposed into a product of the same number thrice.
Let’s discuss the definition and list of perfect cubes of numbers along with the stepwise method to find them.
