Fluid, density?

Question

A fluid of unknown density floats a .25m x .1m x .02m block of wood weighing .35kg. The block has .002m of its smallest side above the surface of the water. What is the density of the block? What is the density of the fluid? I found the density of the block to be 700 kg/m^3. Is this correct? And how do you find the density of the fluid?

Answer 1

to point you on your way.

An object floats because its weight is supported by an equal weight of displaced fluid. So determine the submerged volume of wood which will equla the displaced volume of liquid.

You now know a weight and a volume the answer is just math.
