Answer:

If we assume that the box is a cube with 150 m² surface area

Area of 1 face = 150 m² / 6 = 25 m²

The box will exert a downward force of

Force = mass * acceleration due to gravity

Force = 300 kg * 9.81 m/s² N

Force = 2943 N

The box exerts a pressure ( force / unit area) = 2943 N / 25 m²

Pressure = 117.7 N/m²
