Expert Answer:
cube is floating, therefore
weight of liquid displaced = weight of cube
let the volume of liquid displaced = V
and density of liquid = ρ
and mass of cube = M
then
if liquid is water then ρ = 1000 kg/m3
l = 0.02 m (given)
m= 0.2 kg (given)
putting these value we get a= 0.1 m
= 10 cm
weight of liquid displaced = weight of cube
let the volume of liquid displaced = V
and density of liquid = ρ
and mass of cube = M
then
