How to fix the Not a number value?
Using this script i m facing this error Not a number value that i don t understand,
How can I fix this ?

var cube = function(side) {
this._side = side;
this.volume = function() {
var vol = Math.pow(this.side, 3);
return vol;
};
this.surface = function() {
var totalLength = 12 * this.side;
return totalLength;
};
};
var firstCube = new cube(2);
document.write("Volumul " + firstCube.volume() + "<br>");
document.write("Total length " + firstCube.surface());

Btw, the surface of a cube isMath.pow(side, 2) * 6, just saying.

You assign the value of side to this._side. Therefore you can access it as side inside of the function and as this._side inside of every method (as your methods are inside the function too, both will work). But this.side does not exist, it is not defined, and multiplying it results in Not a Number.
How I would write that:
class Cube {
constructor(side) { this.side = side; }
get volume() { return Math.pow(this.side, 3); }
get surface() { return 12 * this.side; }
}
const cube = new Cube(3);
console.log(cube.volume, cube.surface);
