//7 Kyu
//Building blocks
//Fundamentals, OOP


// 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
// Note: no error checking is needed

// Any feedback would be much appreciated


//Solution 

class Block{

  constructor(arr){
    this.width = arr[0];
    this.length = arr[1];
    this.height = arr[2];
  }
  
  getWidth(){
    return this.width
  }

  getLength(){
    return this.length
  }
  
  getHeight(){
    return this.height
  }
  
  getVolume(){
    return this.getWidth() * this.getLength() * this.getHeight()
  }

  getSurfaceArea(){
    return (2*(this.getWidth() * this.getLength())) + (2*(this.getWidth()* this.getHeight())) + (2*(this.getLength() * this.getHeight()))
  }
}
