Cube (x³) Calculator
Raise any number to the third power and see the intermediate squaring step.
Inputs
x³ (Cube)
343.000000
x² (intermediate)
49.000000
Step by step
Square the number first
7 × 7 = 49
Multiply by x again to get the cube
49 × 7 = 343
Result
7³ = 343
= 343
How it works
Cubing a number means raising it to the third power: x³ = x × x × x. This gives the volume of a cube with side length x. Negative numbers cubed stay negative (e.g. (−3)³ = −27).

x³ = x × x × x

Frequently Asked Questions
Is the cube of a negative number negative?
Yes. Negative × negative = positive, then positive × negative = negative. So (−3)³ = 9 × (−3) = −27.
What is the relationship between cube and cube root?
They are inverse operations. If x³ = y, then the cube root of y is x. For example, 5³ = 125 and ∛125 = 5.
