Water is poured into the Aquarium 32 cm high, 50 cm long and 20 cm wide, the level of which is 2 cm below the edge

Water is poured into the Aquarium 32 cm high, 50 cm long and 20 cm wide, the level of which is 2 cm below the edge. Calculate: a) water pressure on the bottom; b) the weight of the water; c) the force with which water acts on a wall 20cm wide

h = 32 cm = 0.32 m.
l = 50 cm = 0.5 m.
a = 20 cm = 0.2 m.
d = 2 cm = 0.02 m.
ρ = 1000 kg / m3.
g = 9.8 m / s2.
P -?
F -?
Fst -?
The hydrostatic pressure of the liquid at the bottom is determined by the formula: P = ρ * g * h1. Where ρ is the density of the liquid, g is the acceleration of gravity, h1 is the height of the liquid.
h1 = h – d.
P = ρ * g * (h – d).
P = 1000 kg / m3 * 9.8 m / s2 * (0.32 m – 0.02 m) = 2940 Pa.
F = m * g = V * ρ * g = (h – d) * a * l * ρ * g.
F = (0.32 m – 0.02 m) * 0.2 m * 0.5 m * 1000 kg / m3 * 9.8 m / s2 = 294 N.
Fst = Pcr * a * l.
Pav = P / 2.
Fst = P * a * l / 2.
Fst = 2940 N * 0.2 m * 0.5 m / 2 = 147 N.
Answer: P = 2940 Pa, F = 294 N, Fst = 147 N.
