Question

What is relative density? The relative density of substance is greater than 1, what does it signify?

Answer 1

If the reference material is water then a substance with a relative density (or specific gravity) less than 1 will float in water. For example, an ice cube, with a relative density of about 0.91, will float. A substance with a relative density greater than 1 will sink

Answer 2

relative density stands for density of object ÷ density of water if relatively density is greater than 1 it will sink it signifies it's density is greater than that of water
