An ultra-endurance athlete training in an extreme desert environment has a total daily energy expenditure of 35,000 kJ35,000\text{ kJ}35,000 kJ. To maintain a stable core body temperature, 36% of this energy is dissipated via the evaporation of sweat from the skin.

Evaporating 1 cm3 of sweat requires 2.4 kJ of thermal energy.

Calculate the volume of sweat the athlete must evaporate each day. Give your answer in dm3\text{dm}^3dm3.

(Note: 1 dm3=1,000 cm31\text{ dm}^3 = 1,000\text{ cm}^31 dm3=1,000 cm3)
