A rectangular swimming pool is 48 m long and 20 m wide. The shallow edge of the pool is 1 m deep. For every 2.6 m that one walks up the inclined base of the swimming pool, one gains an elevation of 1 m. What is the volume of water (in cubic meters), in the swimming pool? Assume that the pool is filled up to the brim.
Explanation:
Since the elevation increases by 1 m for every 2.6 m,
x=2.62-1=6.76-1=5.76=2.4 m
Since 482.4=20,
The height of the deeper end of the pool is 20 m.
This can be represented as follows,
The total volume of water in the pool,
12×48×20×20+(48×20×1)
⇒ 48× 20 × 11
⇒ 10560 m³
Hence, option (d).
