You need 4 rectangles and two squares * * * * * No, you do not need to have squares: there can be six rectangles - as in a brick shape.
-3
sure , take cube root of 3, that is irrational, but when you cube it you have 3 which is clearly rational! Doctor Chuck aka mathdoc
-8
If you take a look at this graphic on wikipedia http://en.wikipedia.org/wiki/File:The_11_cubic_nets.svg It will show all 11 nets of the cube.

I counted 54 rectangles... But don't take my word for it count them yourself!

depennds on the amount of ice
If you mean by real life examples, then take a standard tissue box. (No, not the cube-shaped one.) Then there's a book, although its rectangles are not the same all around.
It depends on the temperature and the size of the ice cube.
You take apart a few pieces and put a pea size of petroleum Jelly in your cube.
If the box is a cube (all sides perfectly square) then you take the cube root of 9261 and you'll get 21".Check: 21" x 21" x 21" = 9261 cubic inches.If the box has rectangles for sides, then the combinations are limitless.
20 minutes
there's probably 8 but don't take this as your answer cause it might be wrong
There are many different expectations of solving a Rubik's Cube. For some people it may take 11 seconds, but for others it could take up to a month.
It can take on many dimensions but if its a cube then the cube root of 800 will give its equal dimensions in mm
