Final answer:
The total area of the elephant's feet is 0.4 m². The pressure exerted on the ground by the elephant is 150000 Pa or 150 kPa.
Step-by-step explanation:
To calculate the total area of the elephant's feet, we multiply the area of one foot by the number of feet. Since each foot has an area of 0.1 m² and the elephant has four feet, the total area is 0.1 m² x 4 = 0.4 m².
To calculate the pressure the elephant exerts on the ground, we use the formula pressure = force / area. The elephant weighs 60000 N and the total area of its feet is 0.4 m². Therefore, the pressure is 60000 N / 0.4 m² = 150000 Pa (Pascals), which is the same as 150 kPa (kilopascals) since 1 kPa = 1000 Pa.
