• Real depth / apparent depth = refractive index    h1 / 6 cm = μ    =  h1 = 6 μ  cm    h2 / 4cm =  μ    =  h2 = 4 μ  cm         h1 + h2 =  15 cm = 10 μ    =    μ = 1.5 cm The bubble is in the middle of the width of the cube.  So real depth from h1 one side face is equal to (15-h1) of the real depth from the opposite face.
