(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Basic Buoyant Force HW Question

First time doing this, so bare with me:)

1. The problem statement, all variables and given/known data

A 53kg girl dives off a raft4m squarefloating in a freshwater lake. By how much does the raft rise?

Density of water = 1000kg/m^3

Use the equation for buoyant force. Then solve the equation for V.

Of course, volume = L x W x H.

g = 9.8 m/s^2

Fb = weight of girl in Newtons

3. The attempt at a solution

My teacher gives us the equation for buoyant force as Fb = (density)(volume)(acc.due to gravity).

The answer is to be given in cms (centimeters).

Fb = (1000)(???)(9.8)

I am trying to get the volume, knowing that there is4m squared. I am just missing the height.

Thanks for any ideas...
