A cube-shaped tank with a volume of 1 m ^ 3 is filled with oil. What is the pressure force of oil on the bottom of the tank?

According to Pascal’s law:
The hydrostatic pressure inside the liquid at any depth does not depend on the shape of the vessel in which the liquid is located, and is equal to the product of the density of the liquid, the acceleration of gravity and the depth at which the pressure is determined:
P = ρ * g * h, where ρ is the density of the liquid, g is the free fall acceleration of a body raised above the Earth g = 9.8 m / s2, h is the depth of immersion in the liquid.
The volume of the tank is determined by the formula:
V = a³
Find the height of the tank:
a = V ^ (1/3) = 1 ^ (1/3) = 1 m.
The density of neuti according to the reference book is ρ = 800 kg / m³.
We substitute numerical values ​​into our formula, we have:
P = ρ * g * h = 800 * 9.8 * 1 = 7840 Pa
Answer: the oil pressure at the bottom of the tank is 7840 Pa or 7.84 kPa.
