When elephants walk, they keep two feet on the ground at the same time. Assume an elephant weights 3600 kg, and it has circular footprint with radius of 8cm. How much pressure will it exert when it walks? Pressure is force per area, and has units of pascals( N/M^2)

Area of one foot in square meters is π(0.08)² = 0.0201 m²
x2 that is 0.0402 m²
3600 kg is a weight of 3600x9.8 = 35280 newtons
35280 newtons / 0.0402 m² = 878000 N/m² = 878000 Pa = 878 kPa
