A block of wood with volume V floats in water with 0.67V submerged. In oil the block floats with 0.88V of its volume submerged.
(a) Find the density of the wood.
(b) Find the density of the oil.
I honestly have no idea where to begin. I started off with FB = pVg. rearranged it to p = FB/Vg. Plugged in p = Fb/(0.67V)(9.81). That's all the further I got. We won't even get to this in lecture but the prof still insists we do this webassign.
