Calculating Volume Using Buoyant Forces

[F2m185]

I haven't done Physics in some time now and have forgotten how to do some rather simple calculations it seems.

I am trying to calculate the volume of a cube (in cm^3) using the buoyant force of the cube when submerged into water. The given density of water I am using is 1.00g/cm^3 or 1000 kg/m^3. The mass of the cube is 90.6g, and 58.5g submerged.

The buoyant force is 32.1g. Am I missing something here?

Any help?

The mass of the cube is 90.6g, and 58.5g submerged.

I assume you mean that the apparent weight of the submerged cube equals the weight of a 58.5g mass.

The buoyant force is 32.1g. Am I missing something here?

Any help?

So far, so good. (With a similar comment as above.) So what's the volume of the cube? (Hint: Archimedes's principle.)

Thank you for the help!
