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.
The expression "a cube minus b cube a plus b the whole cube" can be mathematically represented as ((a^3 - b^3)(a + b)^3). The difference of cubes (a^3 - b^3) can be factored as ((a - b)(a^2 + ab + b^2)). The expression ((a + b)^3) expands to (a^3 + 3a^2b + 3ab^2 + b^3). Thus, the overall expression combines these factors, but further simplification depends on the specific context or values of (a) and (b).
(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.
