# JavaScript: Volume of a Cube

## JavaScript Math: Exercise-57 with Solution

Write a JavaScript program to calculate the volume of a Cube.

From Wikipedia –

In geometry, a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. The cube is the only regular hexahedron and is one of the five Platonic solids. It has 6 faces, 12 edges, and 8 vertices.

**Sample Data:**

**Sample Solution:**

**JavaScript Code:**

```
// Define a function volume_Cube that calculates the volume of a cube given its length.
const volume_Cube = (length) => {
// Check if length is a number and positive.
is_Number(length, 'Length');
// Return the volume of the cube.
return (length ** 3);
}
// Define a function is_Number that checks if a given value is a number and positive.
const is_Number = (n, n_name = 'number') => {
// If the given value is not a number, throw a TypeError.
if (typeof n !== 'number') {
throw new TypeError('The ' + n_name + ' is not Number type!');
}
// If the given value is negative or not a finite number, throw an Error.
else if (n < 0 || (!Number.isFinite(n))) {
throw new Error('The ' + n_name + ' must be a positive values!');
}
}
// Call the volume_Cube function with valid and invalid arguments and output the results.
console.log(volume_Cube(3.0));
console.log(volume_Cube('3.0'));
console.log(volume_Cube(-3.0));
```

Output:

27 ------------------------------------------------- Uncaught TypeError: The Length is not Number type! at https://cdpn.io/cpe/boomboom/pen.js?key=pen.js-02d7f226-5e95-ffb9-1102-3d13c98d5a6e:7 ---------------------------------------------------------------------- Uncaught Error: The Length must be a positive values! at https://cdpn.io/cpe/boomboom/pen.js?key=pen.js-e084be27-1a02-808e-2e24-5725028ec78d:9
