Answer:
Given that, Mass (m) of an ice block is 125 g and density (d) of ice is 0.92 g/cm³.
We have to find the volume of the ice block.
Density is defined as the ratio of mass per unit volume.
i.e.
Density = \sf{\dfrac{Mass}{Volume}}VolumeMass
Substitute the known values
\implies\:\sf{0.92\:=\:\dfrac{125}{Volume}}⟹0.92=Volume125
\implies\:\sf{Volume\:=\:\dfrac{125}{0.92}}⟹Volume=0.92125
\implies\:\sf{Volume\:=\:135.87\:cm^3}⟹Volume=135.87cm3

• If an object is greater than 1, then it will sink in water. Otherwise, it will float.
• Unit of mass is g (gram) and for volume is cm³. Therefore, the unit of density is g/cm³.
