0.5 m =50 cm

The current water depth is 0.5 meters, so the height of iron submerged in water is 50 cm.

The volume of iron submerged in water is:15×15× 50 =11250 cubic centimeter.

The volume of a container with a height of 0.5m is 60×60×50= 180000 cubic centimeters.

So the volume of water is:180000-1kloc-0/250 =168750 cubic centimeters.

The height of water is:168750 ÷ (60× 60) = 46.875cm.
