Weight of iron block in air = density * volume

= 5 g/cm³ * 125 cm³ = 625 grams

As the density of iron is more than the density of water, it sinks or gets submerged totally in water. We use the Archimedes law.

Buoyancy force = weight of water displaced

= volume of iron block * density of water

= 125 cm³ * 1 g/cm³ = 125 grams

Apparent weight = weight in air - buoyancy force

= 625 - 125 = 500 grams

= 5 g/cm³ * 125 cm³ = 625 grams
