This is a really good question and the answer is quite straight-forward:
First it's important to note that in absolute dark different colours would have no effect on the rate of melting, the rate is dependent on the wavelengths and intensity of the light the surface is exposed to.
If we assume we have two surfaces, one red and one black, and we expose both surfaces to red light of the same intensity. On which surface do you think the ice would melt faster?
The red surface will reflect the red light, however the black surface will absorb the red lightcausing the black surface to increase in temperature. So the ice will melt faster on the black surface.
yes. black absorbs the most heat and will make the cube melt faster. white absorbs the least heat and the cube will melt slower!
black .. because it absorbes all the incombing light rays and sully that energy to melt the ice faster.....
Yes, it can!
112 inch cubes.
Yes
Answering the question and the question in the details below:Ice cubes stick together because the surface of ice is liquid-like and when the ice cubes touch, the surfaces freeze together. For more background, please view the answer to "Why is ice slippery?"The following answer gives some scientific details pertaining to ice:Water freezes at 0 degrees celsius, but the ice that comes out of your freezer is much colder.From the moment you put ice into water, the water gets colder and the ice gets warmer until there is one uniform temperature and all ice has turned to water. You can imagine how if the ice were cold enough, it could freeze all the water.Two cubes of ice at say -10C would easily freeze a thin layer of cold water surrounding them before they get down to the temperature at which they begin to melt.BUT I have noticed that often cubes that are half-melted will still stick together. How can this be? If it has been shrinking, the outer layer should be in the process of melting and therefore not cold enough to freeze its surroundings. I do not know the explanation for this. Perhaps I wasn't watching closely enough. Maybe they froze together when they were larger and for some reason the connections don't melt as fast as the other parts of the ice. More experimentation needed.
Yes, Ice Cubes radiate heat. Consider that an ice cube can be modeled as a grey body (similar to a blackbody, but with a different emissivity) with a temperature = 0 °C. The apply Planck's equation to calculation the radiant exitance of the ice cube. This will give you a measure of the amount of heat given off by an ice cube.
A bunch of ice cubes would melt faster than a block of ice. This is because the ice cubes have a greater surface area exposed to warmer temperatures causing accelerated heat absorption.
If you have got enough cubes, as many as you like.

people want their ice cubes to last longer, so if you make ice cubes in a different shape so they melt slower, people will be happier.
yes

Cubes have a square on each side, but rectangular prisms have rectangles or squares.
