There is a boat with a brick of gold and a brick of iron. Both the blocks are exactly 10 inch in size. If they are dropped into the surrounding water of river.
Which one of the blocks will make the water level higher?
The iron block will make the water level higher.
In actual terms, none of the block will make the water level higher. This is because, while in the boat, they have a larger effect on the water level and they are raising it. But, when they are dropped in the water, they will actually make the water level drop. But, the iron block will make the water level drop much less than the gold block because it is lighter and will have less effect on the water from the boat but will displace the same amount of water as the gold one when dropped into the water.
