Answer 1

Answer:

(A) 666.7

Explanation:

Let,the density of the block be d

Now,as it floats in water with its 2/3 volume below water ,it means, its weight is being balanced by the buoyant force of water on the 2/3rd of its total volume.

So,from equation of force,we can write,

v*d*g=2/3v*1000*g

d=2/3*1000=666.67 kg/m^3
