Maximum pressure from smallest base area Steps:

• Volume V = 1.20 m × 1.50 m × 1.00 m = 1.80 m³
• Mass m = (1.13 × 10³ kg/m³) × 1.80 m³ = 2034 kg
• Weight W = 2034 kg × 9.80 m/s² = 19,933 N
• Smallest area A = 1.00 m × 1.20 m = 1.20 m²; P = W/A = 19,933 N / 1.20 m² = 16,611 Pa = 16 kPa Why D is correct:
• Pressure P = weight / base area; maximum when area is minimized per contact mechanics Why the others are wrong:
• A: Matches density numerically but ignores weight and area
• B: Results from treating lengths as 0.12 m, 0.15 m, 0.10 m (unit error)
• C: From largest area (1.20 m × 1.50 m = 1.80 m²), giving minimum pressure

Final answer: D
