A block of wood floats in fresh water with 0.695 of its volume *V* submerged and in oil with 0.939 *V* submerged. Find the density of **(a)** the wood and **(b)** the oil.

Please give a thorough explantion. The textbook solution does not give enough steps, very unclear.

Thank you!

Step 1

a)

As wooden block floats on water, buoyant force exerted by water on block will be equal to the weight of block acting downwards.

Answer: 695 kg/m^{3}

Step 2

b)

At equilibrium, buoyant force exerted by oil on block will...
