## Homework Statement

A piece of wood floats in water with 65% of its volume under water.Find the relative density of the wood.

## Homework Equations

Buoyancy = (Weight of object) / (Relative density of object)

## The Attempt at a Solution

B = W/s

1= .65/s

s = .65/1

s= .65

My book says this is the right answer but I can't understand how? I guess .65 and 1 are ratios.

But how did they get the one?
