Question
Download Solution PDFThe surface area of water in a swimming pool forms a rectangle with a length of 40 meters and a breadth of 15 meters. The depth of water increases uniformly from 1.2 meters at one end to 2.8 meters at the other end. What is the volume (in m³) of water in the pool?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe pool is a rectangular prism with a sloping bottom. The depth increases uniformly from one end to the other, forming a triangular prism shape.
The depth increases uniformly from 1.2 meters to 2.8 meters. The average depth is:
Average Depth = (1.2 + 2.8) / 2 = 2.0 meters
The surface area of the pool is a rectangle with a length of 40 meters and a breadth of 15 meters:
Surface Area = Length × Breadth = 40 × 15 = 600 m²
The volume of water in the pool is the product of the surface area and the average depth:
Volume = Surface Area × Average Depth = 600 × 2.0 = 1200 m³
Thus, the volume of water in the pool is 1200 m³.
