Volume of the block in water =750/1000*30=22.5cum.
Volume of displace water =block volume in water.

This 22.5 is the force which is equal to the volume of displacing fluid.

75% of the height in the water.

So, volume is 5 * 2 * 0.75 * 3.

Here, volume is equal to length* breadth* height = 2*3*5= 30 CMT.

Density is given so volume in kg = 30*0.75 = 22.5 kg.

Like sand density = 1.9 kg/m^3 and when we multiplied density with CMT then answer comes in kg or tonne same thing is here.

So right and 22.5 but in kg if in m^3 it will be 30.
