A block of wood floats on water, with 65% of its volume under water. Its density (in kg/m³) is approximately:

Correct option is D

Given,
Volume of block wood under water = 65%
=65/100
Density of water = 1000 kg/m³
To find = density of wooden block
Let total volume of wooden block = V
Volume of water removed by wooden block 65/100 V
Let density of water and wooden block are d1 and d2 respectively then from principle of buoyancy
