JavaScript: Volume of a Cuboid

JavaScript Math: Exercise-56 with Solution

Volume of a Cuboid

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

From Wikipedia –
In geometry, a cuboid is a hexahedron, a six-faced solid. Its faces are quadrilaterals. Cuboid means "like a cube", in the sense that by adjusting the length of the edges or the angles between edges and faces a cuboid can be transformed into a cube.

Sample Data:

Sample Solution:

JavaScript Code:

// Define a function vol_Cuboid that calculates the volume of a cuboid given its width, length, and height.
const vol_Cuboid = (width, length, height) => {
  // Check if width, length, and height are numbers and positive values.
  is_Number(width, 'Width');
  is_Number(length, 'Length');
  is_Number(height, 'Height');
  // Return the volume of the cuboid.
  return (width * length * height);
}

// 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 vol_Cuboid function with valid and invalid arguments and output the results.
console.log(vol_Cuboid(3.0, 2.0, 4.0));
console.log(vol_Cuboid('3.0', 2.0, 4.0));
console.log(vol_Cuboid(3.0, -2.0, 4.0));

Output:
