Answer:
,
Explanation:
Depth from 1st side= 10 cm
Depth from 2nd side = 6 cm
10x +6x=24
15x=24
x=24/15
x=1.5

Answer:
Refractive index is 1.5
Explanation:
Depth from 1st side (D) = 10 cm
Depth from 2nd side (d) = 6cm
So.,
Cubes edge = Dx + dx
( Here x is the refractive index of the glass)
24 = 10x + 6x
24 = 16x
x = 24/ 16
x = 3/2 = 1.5
