A cube 10.0 cm on each side has a density of 2.053 x 10^4 kg/m^3. It's apparent weight in fresh water is 192 N. Find the buoyant force.

9 N

Explanation: Given that L = side of the cube = 10cm = 0.1m

Mass = Density * Volume

Let's determine the volume of the cube in m^3.

V = L^3

V = 0.1^3 = 0.001m^3

Mass = 0.001 * 2.053 * 10^4 = 20.53kg

Weight = 20.53 * 9.8 = 201.194

Buoyant force = 201.194 - 192 = 9.194 N

This is approximately 9 N.
