1. Homework Statement

A 2.8 kg rectangular air mattress is 2.00 m long, 0.500 m wide, and 0.100 m thick. What mass can it support in water before sinking?


2. Homework Equations

Density = Mass / Volume
Magnitude of buoyant force = Weight of fluid displaced
Buoyant force = weight of floating object
Weight of object x Buoyant force = Density of object / Density of fluid
Density of water = 1000 kg/m3

3. The Attempt at a Solution

I can't figure out what I would need to do in order to answer the question or what I would need to find.
