Hi..

thickness of the slab = real depth from one face (d) + real depth from the opposite face (d')



now, we know that

refractive index = real depth / apparent depth



thus, for the one face

1.5 = d / 5cm

or

d = 7.5cm



and for the opposite face

1.5 = d'/2cm

or

d' = 3cm

, total thickness of the slab will be

T = d + d' = 3cm + 7.5cm

or

T =7.8 cm

Hope this helps u!!
