**[SOLVED] Basic Buoyant Force HW Question**

First time doing this, so bare with me:)

## Homework Statement

A 53kg girl dives off a raft

**4m square**floating 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

## 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 is

**4m squared**. I am just missing the height.

Thanks for any ideas...
