A board that is $20\mathrm{.}0$ cm wide, $5\mathrm{.}00$ cm thick, and $3\mathrm{.}00$ cm long has a density of $350$ kg$/$m$3.$ The board is floating partially submerged in water of density $1000$ kg$/$m$3.$ What fraction of the volume of the board is above the surface of the water?$$

a$.$

$0\mathrm{.}350$

b$.$

$0\mathrm{.}200$

c$.$

Zero

d$.$

$0\mathrm{.}650$

e$.$

The answer depends on which edge of the board is vertical.$$
