buildingBlocks.js

// Write a class Block that creates a block (Duh..)

// Requirements
// The constructor should take an array as an argument,
// this will contain 3 integers of the form [width, length, height]
// from which the Block should be created.

// Define these methods:

// `getWidth()` return the width of the `Block`

// `getLength()` return the length of the `Block`

// `getHeight()` return the height of the `Block`

// `getVolume()` return the volume of the `Block`

// `getSurfaceArea()` return the surface area of the `Block`
// Examples
//     let b = new Block([2,4,6]) -> creates a `Block` object with a width
//     of `2` a length of `4` and a height of `6`
//     b.getWidth() // -> 2

//     b.getLength() // -> 4

//     b.getHeight() // -> 6

//     b.getVolume() // -> 48

//     b.getSurfaceArea() // -> 88

  constructor(data) {
    this._width = data[0];
    this._lenght = data[1];
    this._height = data[2];
  }
  getWidth() {

    return this._width * this._lenght * this._height;
  }
  getSurfaceArea() {
    return (
      (this._width * this._lenght +
        this._width * this._height +
        this._lenght * this._height) *
      2
