Pressure from weight distributed over total foot area

Steps:

• Calculate weight: force = mass × g = 6000 kg × 9.8 N/kg = 58,800 N.
• Determine total area: 4 feet × 0.2 m²/foot = 0.8 m².
• Compute pressure: P = force / total area = 58,800 N / 0.8 m² = 73,500 Pa = 73.5 kPa ≈ 74 kPa.
• Match to option C.

Why C is correct:

• Pressure is defined as force per unit area (P = F/A), with total force as the elephant's weight (mg) spread over all four feet.

Why the others are wrong:

• A: Underestimates by using single foot area (0.2 m²) instead of total.
• B: Likely divides weight by mass or ignores area multiplication.
• D: Overestimates by using single foot area without dividing properly.

Final answer: C
