FLUID STATICS $153$

$2\mathrm{.}93$ A rectangular block with a specific gravity of $0\mathrm{.}5$ floats in water, as shown in the figure. The density of water is $1000k\frac{g}{m^3}.$ Determine

a$)$ the depth of submergence,

b$)$ the metacentric height and

c$)$ whether the block is stable or not.
