•5*2 = 25mm^2
c-5^2 == 25c^2
i-5^2 === 25i^2
m5^2 = 25m^2
These squares are the basis of the relevant Volumes.

•5^3 =125mg. =>for you 0.005^3 ≠ 0.000000125.m^3.
c-5^3 == 125g. => for you 0.05^3 ≠ 0.000125.m^3
i-5^3 == 125kg. => for you 0.5^3 ≠ 0.125.m^3.
m5^3 =125m^3. ==> for you 5^3 ≠ 125.m^3.

Since the world is made of Matter...including us.
You should first know how to calculate the Volumes p. and G.
Using the relevant units: 1•. 1c..1i..5i..6i..7i..8i..9i..10i..11i etc.

1i * 10i = 10i^2 => for you genius 0.1*1m = 0.1 and not 0.1m^2
1i *1m *2m =1i *10i *20i =200i^3. => for you 0.1 *1 *2 = 0.2
Are you so genius as to eliminate 1m to say 1i *20i = 0.2m. ?

5i * 1m = 5i *10i = 50i^2 ==> for you genius 0.5 *1 = 0.5 ?
5i * 1m *2m = 5i *10i *20i =1000i^3 => for you 0.5 *1 *2 = 1 ?
You are such a genius as to eliminate 5i * 20i = 100i^2. say 1m. ?
In fact, being a genius you don't consider..that 1m^2 *Z=1 =1m^3. ?
Therefore 5i *10i *20i = 1000i^3 Alias 0.5 *1 *2 = 1....m^3 -:))))

Greetings T.n.p. => m2^3 = 8m^3 => 3^3 = 27m^3 => 4^3 =64m^3-:)))
To understand them you need the T.n.p.=> i30^3 =27'000i^3 =27m^3 -:)))
In fact the 3m..complete..... is worth 30dm = 30i. like 4m/0.1 = 40i-:)))

So you will say 3i *30i = 90i^2 as you will say => 1i *3i *30i = 90i^3-:)))
Maybe you find squares p. and volumes p. without making them... depend
on m^2 and m^3. Note: 0.1 *0.3 *3 = 0.09m^3..which *1000i^3 = 90i^3.
It means that everything you do...is all wrong -:))))
