A homogeneous cube with the side \(10\, \mathrm{cm}\)
is in the water. The bottom side is parallel to the water surface
\(10\, \mathrm{cm}\) below
the surface. Find the work required to move the cube to the position when the
bottom side just touches the surface of the water. The mass density of the cube is
\(2\: 000\, \mathrm{kg\, m}^{-3}\), the mass density of the
water is \(1\: 000\, \mathrm{kg\, m}^{-3}\) and the standard
acceleration of gravity is \(g = 10\, \mathrm{m\, s}^{-2}\).
