An exponent of power `3` is called cube of the number.
eg: Cube of `7` is `7^3 = 343`.
Which of the following is a meaning for the word "cube"?
- the 3D shape of equal sides and `90^@` angles between edges
- the 3D shape of equal sides and `90^@` angles between edges
- c shaped tube
The answer is "the 3D shape of equal sides and `90^@` angles between edges".
The exponent cube is representative of "volume of the shape cube, side to the power 3".
What is `8^(1/3)`?
- `2`
- `2`
- `8/3`
The answer is "`2`".
What is `root(3)(125)`?

- `5`
- `5`
The answer is "`5`".
An exponent of power `1/3` or the `3`rd root is called cube root of the number.
eg: Cube root of `64` is `64^(1/3) = root(3)(64) = 4`.

What is the term used to refer "a number to the power of 3"?
- Pronunciation : Say the answer once
Spelling: Write the answer once
The answer is "cube".
What is the term used to refer "a number to the power of `1/3`"?
- Pronunciation : Say the answer once
Spelling: Write the answer once
The answer is "cube root".
Cube of a number : A number to the power `3` is the cube of the number.
eg: `6^3 = 6xx6 xx 6 = 216`
Cube Root of a number : A number to the power `1/3` is the cube root of the number.
eg: `root(3)(216) = 6` as `6^3=216`.
