**[SOLVED] bouyancy problem**

## Homework Statement

If a steel ax and a aluminum piston have the same apparent weights in the water which can be written as

(Pax)(Vax) - (Pw)(Vax) = (Pp)(Vp) - (Pw)(Vp)

where P=rho(density), p=piston, V=volume, and w=water

Find the ratio (Wax/Wp) of their weights in the air. (Neglect the buoyant force in the air.) Assume densities Pax=7.7g/cm^3 and Pp=2.5g/cm^3

## Homework Equations

P=m/v

## The Attempt at a Solution

I do not even know how to start it so any help would be greatly appreciated.
