A rectangular swimming pool is 50 meters long and 25 meters wide. Its depth is always the same along its width but linearly increases along its length from 1 meter at one end to 4 meters at the other end. How much water (in cubic meters) is needed to completely fill the pool?
Explanation:
Volume of the tank = Volume of the cuboid + Volume of the triangular prism
The volume of cuboid will be 50 × 25 × 1 = 1250
The volume of triangular prism = Area of triangle × width = 1/2 × 3 × 50 × 25 = 1875
∴ Total volume = 1875 + 1250 = 3125.
Hence, option (e).
