A brick measuring 5x10x20 cm is completely submerged in water. Calculate the buoyancy of the brick.

| The buoyancy force that acts on the brick is the Archimedes force, which can be calculated using the formula:
Fa = ρ * g * V, where ρ is the density of water (according to the table ρ = 1000 kg / m3), g is the acceleration of gravity (we take g = 10 m / s2), V is the volume of the brick (according to the condition, the dimensions of the brick are 5x10x20 cm ; when translating dimensions from cm to m: V = 0.05 * 0.1 * 0.2).
Let’s make a calculation:
Fa = ρ * g * V = 1000 * 10 * 0.05 * 0.1 * 0.2 = 10 N.
Answer: The buoyant force acting on the brick is 10 N.
