A boy weighing 70 kg is standing on the sand. Calculate the pressure on if you are resting on your feet, whose surfaces add up to 0.035 m2 and if you are resting on diving fins of 0.300 × 0.42 m each

Explanation:

Pressure = force / area

If you are standing on your feet:

P = (70 kg × 10 m/s²) / (0.035 m²)

P = 20,000 Pa

If you are standing on diving fins:

P = (70 kg × 10 m/s²) / (2 × 0.30 m × 0.42 m)

P ≈ 2,800 Pa
