Answer :
Final answer:
To fill the rectangular swimming pool half full, we calculate the full volume and then divide by 2. The full volume is 3000 cubic meters, so half of that is 1500 cubic meters. The answer is C. 1500 cubic meters.
Explanation:
The question asks us to calculate the volume of water needed to fill a rectangular swimming pool to half its depth. The dimensions of the pool are given as 25 meters in width, 40 meters in length, and a uniform depth of 3 meters. To find the volume of water required to fill the pool halfway, we first calculate the full volume of the pool and then divide that number by 2.
Volume of the full pool = length × width × depth
Volume = 40 m × 25 m × 3 m = 3000 cubic meters
To fill the pool half full, we need half of the full volume:
Volume needed = ½ × 3000 cubic meters = 1500 cubic meters
Therefore, the correct answer to the question is: C. 1500 cubic meters
