A cubed number is what you get when a number is used in a multiplication three times.

Example: 4 x 4 x 4 = 64, so 64 is a cubed number.

The first twelve cube numbers are:

1. 1
2. 8
3. 27
4. 64
5. 125
6. 216
7. 343
8. 512
9. 729
10. 1000
11. 1331
12. 1728 (a dozen gross)

A cubic number is said to be a number which is obtained by multiplying the same number three times. In simple Cube=Square of a number*number.

Example: 2 x 2 x 2 = 8, so 64 is a cubic number.

The first twelve cube numbers are:

1. 13=1
2. 23=8
3. 33=27
4. 43=64
5. 53=125
6. 63=216
7. 73=343
8. 83=512
9. 93=729
10. 103=1000
11. 113=1331
12. 123=1728

What are the first 12 cube numbers?

What is a cube number?
A cube number (or a cube) is a number you can write as a product of three equal factors of natural numbers.
Formula: k=a*a*a=a³ (k and a stand for integers.)

 1 1 =1 × 1 × 1 2 8 =2 × 2 × 2 3 27 =3 × 3 × 3 4 64 =4 × 4 × 4 5 125 =5 × 5 × 5 6 216 =6 × 6 × 6 7 343 =7 × 7 × 7 8 512 =8 × 8 × 8 9 729 =9 × 9 × 9 10 1000 =10 × 10 × 10 11 1331 =11 × 11 × 11 12 1728 =12 × 12 × 12

## Understand and learn the words: square, positive and negative square root, cube and cube root, learn squares up to 15x15 and cubes up to 5 cubed

### Square numbers

'Squaring' a number is essentially multiplying it by itself.

22 means '2 squared', or 2 x 2.

The small 2 is an index number, or power. It tells us how many times we should multiply 2 by itself.

Similarly 52 means '5 squared’ or 5 x 5.

And 102 means '10 squared', or 10 x 10.

So, 12 = 1 x 1 = 1

22 = 2 x 2 = 4

32 = 3 x 3 = 9

42 = 4 x 4 = 16

52 = 5 x 5 = 25

The square numbers can be written in a sequence:

1, 4, 9, 16, 25… are known as square numbers.

### Square roots

The opposite of a square number is a square root.

We use this symbol √ to mean square root.

So we can say that √4 = 2 and √25 = 5.

However, this is not the whole story, because -2 x -2 is also 4, and -5 x -5 is also 25.

So, in fact, √4 = 2 or -2. And √25 = 5 or -5.

The square root can also be shown as an index number of 1/2.

### Cube numbers

23 simply means ‘2 cubed’ or 2x2x2.

The cubed symbol, ‘3’, tells us how many times to multiply the number its attached to.

So, 33 means 3x3x3

13 means 1x1x1 = 1

2means 2x2x2 = 8

33 means 3x3x3 = 27

4means 4x4x4 = 64

### Cube roots

The opposite of a cube number is a cube root. We use the symbol to mean cube root. Each number only has only one cube root, unlike square roots which can have both positive and negative versions of the same number.

Similar to square roots, cubed roots can also be shown with an index number 1/3, as an alternative to the symbol.

Examples:

3√8 = 2

3√27 = 3

3√64 = 4

3√125 = 5

### Squares upto 15x15

·       12 = 1 x 1 = 1

·       22 = 2 x 2 = 4

·       32 = 3 x 3 = 9

·       42 = 4 x 4 = 16

·       52 = 5 x 5 = 25

·       62 = 6 x 6 = 36

·       72 = 7 x 7 = 49

·       82 = 8 x 8 = 64

·       92 = 9 x 9 = 81

·       102 = 10 x 10 = 100

·       112 = 11 x 11 = 121

·       122 = 12 x 12 = 144

·       132 = 13 x 13 = 169

·       142 = 14 x 14 = 196

·       152 = 15 x 15 = 225

### Cubes upto 5

·       13 = 1 x 1 x 1 = 1

·       23 = 2 x 2 x 2 = 8

·       33 = 3 x 3 x 3 = 27

·       43 = 4 x 4 x 4 = 64

·       53 = 5 x 5 x 5 = 125
