Without looking it up, I believe it comes from the fact that if you have a square, and it's, say 2 units long and 2 units wide, the area of the square is 4 square units. (if it was 2 ft x 2 ft then area is 4 square feet). 2 x 2 is the same as 22
Likewise to find a volume of a cube, multiply length by width by height. Since they are all the same, you have (side)3 is the volume. Something to the third power is called 'cubed'. Since we live in a three dimensional world, as far as we know, nobody has come up with a term for fourth power, fifth power, etc.
