title: Calculating cubic volume between 2 coordinates
body: <p>I need a little bit of help.
  I basically want to calculate the block count between two coordinates in the world, but I'm not too good at math as you can see, so If you have a solution please write it to me.
  This is important so please write it, I'd appreciate it!</p>
  
  <pre><code>int x1 = 0, y1 = 0, z1 = 0, x2 = 0, y2 = 0, z2 = 0;
  x2 = x // pos x in the coord
  y2 = y // pos y in the coord
  z2 = z // pos z in the coord
  x1 = x;
  y1 = y;
  z1 = z;
  int a = Math.abs(Math.abs(x1)-(Math.abs(x2)));
  int b = Math.abs(Math.abs(y1)-(Math.abs(y2)));
  int c = Math.abs(Math.abs(z1)-(Math.abs(z2)));
  if(x2 != 0)
  int volume = a*b*c;
  </code></pre>
