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. I will mark as brainlist

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

Answer 2

The overall density is 0.66g/cm³.

Explanation:

•We know that density is inversely proportional to the volume.

•where d1= density outside.

d2= density inside

v1= volume outside

v2= volume inside

•By the condition,

d1/d2 = v2/v1

•Therefore,d1/d2 = 40/60

•then,d1/d2 = 0.66g/cm³.

•As it same material(fire wood ),The density of the fire wood is 0.66g/cm³.
