By its size
You can measure it, and there are tables giving the density of pure water at various temperatures.
An object will sink if its density is greater than the liquid in which it is placed; it will float if its density is less.
Based on its density. For example, waters density is 1 g/mL. If something has a density greater than 1 g/mL it will sink in water. If it has a density less than 1g/mL it will float in water.
If an object has less density than water (or whatever liquid you are considering), it will float. And if it has more density then the liguid you are considering it will sinq

Add the two densities!
No, because you can predict if an object will sink or float mostly on density.
The answer depends on what you were trying to predict.
Because that's how life is. If the density is greater than the density of water it will sink. If less, it will float.
If its density is less than 1 it will float in water. If its density is more than 1, it will sink in water.
body density
An object will sink if its density is greater than the liquid in which it is placed; it will float if its density is less.
if the density of the object was higher than 1 then it will sink if less than 1 it will float in water....
If the object's density is greater than the density of the liquid in which it is placed, it will sink. If the density is less, it will float. You can use math to calculate the density, if you know an object's mass and volume. Density is defined as mass divided by volume.
