Is my working correct?

Actual amt of water to fill 2nd layer = 8.375 – 3.875 = 4.5 l

Difference between 1st and 2nd layer = 4.5 – 3.875 = 0.625 l (difference is 5 cubes less)

Vol of each cube = 0.625 / 5 cubes = 0.125 l

Please help to solve if my answer is wrong. Thank you.

Yes it is correct.

Solid occupies the space of the liquid in layer 1 (lesser water)

Liquid occupies the space of the removed solid (more water)

The added water volume = volume of the solid removed
