Determine the mass of a body measuring 2 × 3 m, which is exerted by a pressure of 100 Pa.

Initial data: the size of the base of the body is 2×3 m; P (pressure that the body creates) = 100 Pa.

Constants: g (acceleration due to gravity) = 9.81 N / kg ≈ 10 N / kg.

1) Calculate the area of the base of the body: S = 2 * 3 = 6 m2.

2) Determine the desired body mass: P = F / S = m * g / S, whence m = P * S / g = 100 * 6/10 = 60 kg.

Answer: The body has a mass of 60 kilograms.
