B)Calculate the density of the oil.

Part A:

The mass of the object is 33.027 kg

and the mass when submerged in water is 29.561 kg.

This means the volume would be 3.466 because the volume of the object is the volume of the displaced water.

So, 33.027 kg/ 3.466 kg =9.5288 and the answer is wrong.

What am i doing wrong.

As for B i dont know how to tackle it
