Problem

A cube with edges of length

0.15\,\text{m}

is completely submerged in freshwater (

\rho = 1.0 \times 10^{3}\,\text{kg}\,\text{m}^{-3}

) on Earth (

g = 9.8\,\text{m}\,\text{s}^{-2}

). What is the magnitude of the buoyant force acting on the cube? (a)

16.5\,\text{N}

(b)

3.3\,\text{N}

(c)

33\,\text{N}

(d)

220\,\text{N}
