At the bottom of the ocean, they found a statue of Poseidon weighing 810 kg made of marble

At the bottom of the ocean, they found a statue of Poseidon weighing 810 kg made of marble (density 2700 kg / m3) find the Archimedes force acting on the statue in seawater (water density 1030 kg / m3)

The force of Archimedes is found by this formula
Fa = g * pzh * Vt
Before substituting the value, you need to find the volume of the body by the formula
Vt = m / pt
VT = 810/2700 = 0.3 (m ^ 3)
To find this force, everything is there, it remains only to substitute the values
Fa = 10 * 1030 * 0.3 = 3090 (N)
Answer: Fa = 3090 (H)
