How would you gently and kindly un-muddle the author's intent and deepen their own understanding?

So with the Pap over and the mocks around the corner it’s back to solid theory for a month with LCPE I have four practice papers I made during lockdown for students to practice questions if you want a copy just let me know

Draw an edge and mark two of its three units.
Form a rectangle, 3*5, by drawing a five-unit edge perpendicular to it. Mark four of its units.
You will get a smaller rectangle with dimensions 2*4.
=> (2/3)*(4/5) = (2*4)/(3*5)=8/15

'Annihilate the Cuboid'
The cuboid below is made of blue cube, x^3, red cuboid (x^2)*3, white cuboid (x^2)*-1, white cuboid x*3*-1.
Forward, right, up is indicated by +, backward, left, down by -.
cuboid's description:
(x+0)(x+3)(x-1)
x=0;-3;1 annihilate cuboid.

Find the cuboid's (x+a)(x+b)(x+c) edges a,b and c
a,b,c are integers
a)
Given a+b+c=9
ab+ac+bc=20
abc=12
b
Given a+b+c=9
ab+ac+bc=24
abc=20
c
Given a+b+c=9
ab+ac+bc=-21
abc=11

I'm starting with this project, however I invite you to join the movement, because I want to find new ways for everyone to learn how to and it is happening. We are reinventing together how learning works. And If I am right about these new teaching methods.., oh my!

There's lots of questions like which is larger, 253²³ or 23²⁵³?

First, a hint: if both numbers are integers larger than 2, the answer is ALWAYS that the (smaller)^(larger) > (larger)^(smaller).

But here are ALL the answers, followed by the proofs.
