m = 300 kg.
P = 150 kPa = 150,000 Pa.
g = 10 m / s2
S1 -?
P = F / S, where F is the force that acts on the area S.
F = m * g – gravity acts on the body.
S = 4 * S1 the machine has 4 legs.
P = m * g / 4 * S1.
S1 = m * g / 4 * P.
S1 = 300 kg * 10 m / s2 / 4 * 150,000 Pa = 0.005 m2.
Answer: S1 = 0.005 m2.
