How to snap while scale to an exact size in Blender 2.8

Assalamualaikum

Hi guys. This is my latest tutorial in Blender.

A few days ago I’ve got a question from one of my students at Udemy. Because it will just too long to explain the answer in just a normal text form, I decided to create this tutorial to explain every aspect of the topic.

Snapping while scaling is actually just one of the 4 methods discussed in this video. I hope you find this video helpful.
