Let’s look at the cube of numbers from 1 to 50

Number Cube
1 1
2 8
3 27
4 64
5 125
6 216
7 343
8 512
9 729
10 1000
11 1331
12 1728
13 2197
14 2744
15 3375
16 4096
17 4913
18 5832
19 6859
20 8000
21 9261
22 10648
23 12167
24 13824
25 15625
30 27000
35 42875
40 64000
45 91125
50 125000

Let’s see some pattern in it, and find properties of cube numbers

 

Number of zeroes at the end of a perfect cube is always odd

Example :

25000 is a perfect cube

1000 is a perfect cube

But, 80000 is not a perfect cube

4000000 is also not a perfect cube

 

Cube of even numbers are always even,

Cube of odd numbers are always odd

Example :

Cube of 2 is 8,

Cube of 6 is 216

And

Cube of 7 is 343

Cube of 9 is 729
