Question

when does a body float in a liquid

Answer 1

when Boody's density is lesser

Answer 2

If body's density is less than liquid, then it floats on water The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. To find the density of any object, you need to know the Mass (grams) of the object, and its Volume (measured in mL or cm³). Divide the mass by the volume in order to get an object's Density.
