Calculating the cube of a number means multiplying that number by itself three times. A simple way to calculate the cube of a number is to first multiply the number by itself, and then multiply the result by the original number. According to provided information, an easy way to write 3 cubed is 33.
Here’s a breakdown with examples:
Understanding Cubed
Cubing a number is a mathematical operation that raises the number to the power of 3. This is equivalent to multiplying the number by itself three times.
How to Calculate Cubed
Here's a step-by-step approach:
- Identify the number: Determine which number you want to cube.
- Multiply the number by itself: Perform the first multiplication.
- Multiply the result by the original number again: This final multiplication gives you the cube of the number.
Examples
-
Example 1: Calculate 3 cubed (33)
- First, multiply 3 by 3: 3 x 3 = 9
- Then, multiply the result (9) by 3: 9 x 3 = 27
- Therefore, 3 cubed (33) = 27
-
Example 2: Calculate 4 cubed (43)
- First, multiply 4 by 4: 4 x 4 = 16
- Then, multiply the result (16) by 4: 16 x 4 = 64
- Therefore, 4 cubed (43) = 64
-
Example 3: Calculate 5 cubed (53)
- First, multiply 5 by 5: 5 x 5 = 25
- Then, multiply the result (25) by 5: 25 x 5 = 125
- Therefore, 5 cubed (53) = 125
Formula
The general formula for cubing a number (let's call it 'x') is:
x3 = x x x
Summary
| Number (x) | Calculation (x x x) | Cube (x3) |
|---|---|---|
| 2 | 2 2 2 | 8 |
| 3 | 3 3 3 | 27 |
| 4 | 4 4 4 | 64 |
| 5 | 5 5 5 | 125 |
