Density is a physical property of all materials and represents how much mass the material has per unity of volume. If the density is higher than that of water, the material floats. Lower than it sinks.

Materials sink or float in water based on their density. If an object is denser than water, it will sink; if it is less dense, it will float. The buoyant force of water pushing up on an object counteracts the force of gravity pulling it down.

although the shape of material decides whether it sink or float, it also depends on the material. for eg. an iron plate with hole will sink but a thermocol piece will not. if there is two materials of same shape and type, the one with hole have greater possibility of sinking.

Buoyancy is determined by density. If a material has a lower density than the liquid around it, it will float.

because the density of the soil is greater than the density of the water

Not every type of materials with holes will sink in the water. Only the materials which has more density than the water will sink.
