It means back.
----
b means back 2 layers (Back and center)
B means the back 1 layer.
(a+b)cube = a cube + b cube + 3a square b + 3ab square
The volume of Cube B is 216 cm3
'a' minus 'b' whole cube is equal to 'a cube' minus 'b cube' minus (3 a square b ) plus (3 a b square) . .. .....thanks
(a3-b3) = (a-b)(a2+ab+b2)
The cube of A plus B is either A**3 + B or (A + B)**3 depending on what you intended to be cubed.
(a3-b3) = (a-b) (a2+ab+b2)
a3+b3=(a+b)3-3a2b-3ab2
Acube -bcube
This is the formula: (a3)+(b3)=(a+b)(a2-ab+b2)
Consider a binomial (a+b). The cube of the binomial is given as =(a+b)3 =a3 + 3a2b + 3ab2 + b3.
It is equal to a^3 + b^3. It can also be expressed as (a + b)*(a^2 - ab + b^2) or (a^6 - b^6)/(a^3 - b^3) or many other expressions.
