There are 9 cubes joined together in the shape of an l if this is dipped in red paint and then taken apart how many faces will be red?

Total number of faces = 9*6 = 54
Number of "hidden" faces = 2*(9 - 1) = 16
So number of painted faces = 54 - 16 = 38

Does taking your Rubix Cube apart and putting it back together ruin it?
No, it doesn't. The structure of the cube is designed so that you can take it apart and put it back together. Most world-record holders take apart their cubes to lubricate them. So, yes, it is perfectly fine to disassemble to a Rubik's cube.
Why does two ice cubes on pressing stick together?
It is not always that case that the ice cubes will be joined. For example, if the experiment is conducted in a sufficiently cold environment, then the cubes will not generally be joined after merely pressing them together with the hands. It will be necessary to conduce an experiment to see at what temperature they will fail to join. Such an experiment could start at minus 5 degrees Celsius since it seems reasonable to suppose that is cold enough. At sufficiently high temperatures (surely room temperature but possibly much lower), the cubes will join because they are already starting to melt at the surfaces exposed to the air. By pressing them together, the touching surfaces are no longer exposed to relatively warm air and so they are effectively cooled by the surrounding ice. If the cooling is sufficient then the melted surfaces will re-freeze. Since the surfaces are in contact with each other, they will be joined.

Calcite perhaps (although it does not form cubes).

Fondue is hot cheese (or in some cases, chocolate) melted to the consistency of a sauce, into which bread or fruits are dipped. It can also mean cubes of meat or seafood cooked in hot oil and then dipped in any of several kinds of sauces.
What can you use to make an igloo for a diorama?
sugar cubes and either white glue or a gluegun. do notuse a glue stick to glue the sugar cubes together, because they'll probably fall apart. if you use a gluegun, dont put to much glue on one sugar cube because it might melt it. hope it helps.
What is a mineral that has a colorless chunk that breaks apart into cubes it has no luster and is soft enough to be scratched by fluorite?
The mineral described is likely halite, also known as rock salt. Halite is colorless, often forms cubic crystals, has a lack of luster, and a hardness of around 2.5 on the Mohs scale, making it prone to being scratched by materials like fluorite.
Why do ice cubes stick together at times?
Ice cubes can stick together when they start to melt slightly on their surfaces and then refreeze, creating a bond between the cubes. This phenomenon is more likely to occur in humid environments where moisture can promote the formation of ice bridges between the cubes.
Where can I find a video of somebody taking 6 stickerless rubik's cubes and popping the cubies apart then making 6 new cubes - one of each color?
There are currently no videos of that, but if you want, you can make one! there are cubes available for only $2,
