# JavaScript: Volume of a Pentagonal Prism

## JavaScript Math: Exercise-62 with Solution

Write a JavaScript program to calculate the volume of a prism using only its height and one of its hexagonal sides.

In geometry, the pentagonal prism is a prism with a pentagonal base. It is a type of heptahedron with seven faces, fifteen edges, and ten vertices.

Sample Data:

Sample Solution:

JavaScript Code:

``````// Define a function volume_Pentagonal_Prism that calculates the volume of a pentagonal prism given its base edge and height.
const volume_Pentagonal_Prism = (base_edge, height) => {
// Check if the base edge and height are numbers and positive.
is_Number(base_edge, 'Base Edge');
is_Number(height, 'Height');
// Return the volume of the pentagonal prism.
return (1/4 * height * base_edge * base_edge * Math.sqrt(5 * (5 + 2 * (Math.sqrt(5)))));
}

// 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_Pentagonal_Prism function with valid and invalid arguments and output the results.
console.log(volume_Pentagonal_Prism(4.0, 8.0));
console.log(volume_Pentagonal_Prism('4.0', 8.0));
console.log(volume_Pentagonal_Prism(4.0, -8.0));
```
```

Output:

```220.22110727538777
