What is the ratio of melting times for one iceberg to another twice its mass?

I would guess melting time with all other conditions constant is proportional to surface area that is exposed to the warmer air. There's no definite coupling between surface area and mass. A fractal surface can have many times the surface area of a smooth surface for a given mass.

The melting is due mainly to the water the iceberg is floating in.
