which dissolves faster, a cube of sugar or granulated sugar and why? what does this have to do with surface area?

Greater surface area, more area is exposed to the substance.

Larger surface area dissolves faster. Thin of it this way if you threw a bog chunk of salt in water and grains of salt which would dissolve first.
The grains right. Well they are the same thing so this has to do with surface ares. Essentially the water can "attack" grains of salt all at once. But a chunk it has to dissolve the outside layers of the chunk before it can get to the inside layers.

Greater surface area because there is more area in contact with the dissolving solvent, thereby easier to dissolve.

The greater the surface are (to mass ratio) the faster the dissolution rate.
