Iron is a dense metal, not low density. Its density is around 7.87 g/cm³ at room temperature.
Iron sinks because it is denser than water, so its weight is greater than the weight of the water it displaces. However, an iron boat floats because its overall density is less than that of water, due to its hollow design which displaces enough water to provide buoyancy. The shape and volume of the boat allows it to float despite being made of a dense material like iron.
If a boat with too much cargo is sinking, it means the combined density of the boat and cargo is greater than the density of water. Water has a density of 1 g/cm^3, so anything with a greater density will sink. To stay afloat, an object must have a density less than that of water.
The density of iron ore is variable. Iron ore refers to a rocktype that contains iron minerals. The type and concentration of the iron minerals as well the type and concentration of non-iron minerals determines the density of the iron ore. Typical high grade iron ore is approximately 65% hematite and 35% other (commonly silicate). The density of hematite is approximately 5 g/cc and a general density for crustal rocks (silicates) is approximately 2.67 g/cc. Therefore iron ore that is 65% hematite and 35% silicate would have a density of approximately 4 g/cc.
To change the overall density of a boat, you can add or remove weight from the boat. Adding weight, such as ballast or cargo, will increase the overall density, while removing weight will decrease it. Adjusting the distribution of weight within the boat can also impact its density.
The iron boat is an "empty shell" with air filled space inside, reducing its density compared to the iron cube which is iron all the way through.
The density of Galvanized Iron is 7850 kg/m3. Density of steel is equal to the density of galvanized iron

Iron is more dense than silicon.
That question has no answer, because I don't own a boat. But regarding any boat in general, if the boat is afloat, then its density is less than 1.0 .
Iron has a greater density.
No, the density of copper is less than iron. Copper has a density of about 8.96 g/cm3, while iron has a density of about 7.87 g/cm3.
if they are both made of iron and no other impurities the density is the same

When the density of entire assembly (boat, peoples, products, equipments, water etc.) has a density greater then the water density the boat is sinking.
No, the density of a kilogram of iron is greater than the density of 1 gram of iron. Density is a measure of how much mass is contained in a given volume, so a kilogram of iron has much more mass in the same volume as 1 gram of iron, leading to a higher density.
No, cotton has a density of 1.54-1.56 g/cm³ while iron has a density of 7.874 g/cm³
