Consider equal sized wood cube and cork cube maintained by strings in a fluid as below.

Fluid surface

The density of fluid is $1\mathrm{.}30\frac{g}{c}{m}^3$ and the density of wood is $0\mathrm{.}810\frac{g}{c}{m}^3$ and the density of cork is $0\mathrm{.}200\frac{g}{c}{m}^3.$

$7.$ From the figure which one has greater buoyant force? Calculate each buoyant force.
