If water density is considered the answer must be .66.

Here,
Dry density, Yd=1.6g/cc.
Specific Gravity, G=2.56.
[Consider, water density, Yw as 1g/cc].
Porosity, n= e/1+e.
Void ratio, e= (GYw/Yd) -1=((2.5*1) /1.6)-1=0.6.
Then, porosity, n= e/1+e=0.6/(1+0.6) =0.375.
Dry density, Yd=1.6g/cc.
Specific Gravity, G=2.56.
[Consider, water density, Yw as 1g/cc].
Porosity, n= e/1+e.
Void ratio, e= (GYw/Yd) -1=((2.5*1) /1.6)-1=0.6.
Then, porosity, n= e/1+e=0.6/(1+0.6) =0.375.

Answer is 0.65 by taking the value of unit water.

By using the density of water the answer is 0.66.

The water density is given as 1.84 g/cc , then how the answer is 375?

Here, e is the void ratio. What is the actual formula to finding out the value of porosity? Please tell me.
