How to draw a cube by hand: Measuring System #1 - video 1 of 3

Here is a series of videos, this is part 1 of 3 - Measuring System #1, that show how to draw a perfect cube by hand. The concept is to first do them mechanically so that later on you can practice them by eyeballing the proportions. After drawing them mechanically, you would then draw the same cube mimicking the scale and size of it until you can do them without using a reference.
Ultimately you want to train yourself in how to draw cubes or cubed space so that you are not using rulers at all, and that you know that you have drawn a cube, not a rectangular box.
