Why must a substance be in the powder form before dissolving it?

The actual surface area of the substance is larger when it's in powdered form, and as dissolving only happens at the surface area, dissolving a powder is a faster process.
It is not an absolute necessity , though. When the substance is not powdered, it will dissolve as well, as the amount you can dissolve is only dependent on the substance involved. However, in powdered form, it will dissolve quicker.
