From Archimede's principle, the buoyant force is given by:

$\overline{){{\mathbf{F}}}_{{\mathbf{b}}}{\mathbf{=}}{\mathbf{\rho}}{{\mathbf{V}}}_{\mathbf{d}\mathbf{i}\mathbf{s}\mathbf{p}}{\mathbf{g}}}$

A block of wood is floating in a pool of water.

a) Is the buoyant force acting on the block greater than, less than, or equal to the weight of the block? Explain.

b) Is the volume of the fluid displaced by the block greater than, less than, or equal to the volume of the block? Explain.
