675g/cm³ is the density of the liquid
Here we have given that
density of wood be ρ.
the volume of the block be V
The volume of the block =1/4 v
The volume of the immersed block (v) =V-1/4V=3/4V
We know the weight of the block = the weight of the water displaced by the submerged part of the block.
i.e. V x ρ x g
= 3/4 x900g/cm³
= 675g/cm³
Density is a measure of mass divided by the volume of an object. Defined as mass per unit volume. here from the above equation we have substituted the given value and we got the answer as 675g/cm³
