Question

a fire wood board floats in fresh water with 60 percent of its volume under water. the density of the wood in g/cm^3is

Answer 1

Hey
Here is your answer
====================================
density is inversely propotional to volume
so
density outside/density inside=volume inside/volume outside

d1/d2=40/60
d1/d2=0.66g/cm^3

Now as material is same therefore overall density is 0.66
