You increase the surface area
The "Surface Area" of the solid figure. Note, the word "total" in the answer above is not correct/needed - there can not be anything less than a surface area of a solid figure.
Volume is how much an object can store - like how much can you put inside a box. Surface area is the sum of the area of an objects surfaces - such as if you have a box, find the area of one side. Then you just multiply it by 6 (because a box have 6 faces) to get the total area of an object's surface.
It will increase it, as more of the outer surface of the solid is incontact with the liquid that it is dissolving in. :)
