A swimming pool measures 24 meters in length and 15 meters in width. When several men enter the pool, the water level rises by 1 cm. If each man displaces an average volume of 0.1 cubic meters of water, how many men are in the pool?
Explanation
The volume of water displaced equals the surface area of the pool multiplied by the rise in water height: 24 m × 15 m × 0.01 m = 3.6 m³. Since each man displaces 0.1 m³, the number of men is 3.6 ÷ 0.1 = 36.
