(x2 + x2)=
(ax + b)3 = a3x3 + 3a2bx2 + 3ab2x + b3
The definition of a perfect cube is the cube of a number n is its third power. This is formula that is used for finding volume.
Because that's the definition of a cube.
A 3d square

There can be no such cube since, by definition, all edges of a cube have the same length.
There can be no such cube since, by definition, all edges of a cube have the same length.
If it is a centimetre cube then, by definition, its edge is 1 centimetre.
(x+2)3 =(x)3+3(x)2(2)+3(x)(2)2+(2)3 =x3+6x2+12x+6
You know it is three by definition
The cube root of the expression 403 is 40 itself. This follows from the definition of cubes and cube roots.
A cube, by definition, has six sides. There cannot be a 40-sided cube.
