Answer 2

Rise in water level will be same.

Explanation:

Given that,  

A rectangular block is 10 cm, 10 cm and 15 cm in size is floating in water with 10 cm side vertical.

We know that,

Rise of water level depends on the volume of displaced water.

Mass of block is same in both condition.

We need to calculate the water level

Using buoyant force

$W_{b}=F_{bu}$

$mg=V\rho_{w}g$

Here ,The volume of displaced water depends upon the mass of block.

The volume of water not change whether the block floats with 10 cm side vertical or 15 cm side vertical.

Hence, Rise in water level will be same.
