Homework Statement
Find: (a) volume of plank (b) bouyant force (c) density of plank
mass plank = 877kg
mass bricks loaded on plank = 2.3 * 74 = 170.2
plank if floating level with surface of lake
Homework Equations
p = m/vol
v = l w h
Fb = pfluid x g x volume
The Attempt at a Solution
How does one calculate volume without known dimensions (only mass is know). It can not be derrived from density equation because density of plank is not given (and it varies a great deal)
