Because 2 to the third power is the numeric value of the volume in cubic units of a cube that is 2 length units on each edge.

Why do you think squared and cubed are used to indicate the second and third power?
Because the area of a square is numerically equal to the square of the length of its sides and the volume of a cube is numerically equal to the cube of the length of its sides.
What is an algebraic equation and what is an algebraic expression?
i think so...an algebric expression is that which involves algebric terms while an algebric expression is that algebric expression which involve an inequality sign.

Is the number 2 a cubed number?
No.I think you mean "Is the number 2 a cubic number?" meaning, "Is there any number cubed that will equal 2?".The first cubic number is 1 (13), then 8 (23). So the cubic numbers skip straight past 2.But really if you're asking "Is 2 a cubed number?", then yes it can be. A cubed number would just suggest, "can you cube the number 2"? And yes, 2 cubed = 8.

How can power corrupt someone by not working?
I don't know what connection that not working has to the corrupting effects of power. If someone said this to you, you should ask them what they meant. The expression is "Power corrupts, absolute power corrupts absolutely". It means that people who hold power sometimes believe that they can do what they want, that the rules don't apply to them. "Absolute power corrupts absolutely", means that when someone has complete control, like a dictator, the chance that they are not corrupt in some way is almost impossible. I don't think that this has anything to do with someone or something not working.
