Calculating the volume of water is essential for various applications, such as filling a pool, determining irrigation needs, or understanding container capacities. Here’s a guide on how to calculate water volume for different shapes and scenarios:

How to Calculate Water Volume

1. For Rectangular or Cuboidal Containers:
   • Formula: Volume = Length × Width × Height
   • Example: A tank is 4 meters long, 3 meters wide, and 2 meters high.
     • Calculation: Volume = 4 × 3 × 2 = 24 cubic meters
2. For Cylindrical Containers:
   • Formula: Volume = π × Radius² × Height
   • Example: A cylindrical tank has a radius of 2 meters and a height of 5 meters.
     • Calculation: Volume = π × 2² × 5 ≈ 3.14 × 4 × 5 ≈ 62.8 cubic meters
3. For Spherical Containers:
   • Formula: Volume = (4/3) × π × Radius³
   • Example: A spherical tank has a radius of 3 meters.
     • Calculation: Volume = (4/3) × π × 3³ ≈ 4.19 × 27 ≈ 113.1 cubic meters
4. For Conical Containers:
   • Formula: Volume = (1/3) × π × Radius² × Height
   • Example: A conical tank has a radius of 1.5 meters and a height of 4 meters.
     • Calculation: Volume = (1/3) × π × 1.5² × 4 ≈ 4.19 × 2.25 × 4 / 3 ≈ 11.8 cubic meters
5. For Irregular Shapes:
   • Using Water Displacement: Fill the container with water and measure the volume of water displaced.
