How to calculate the volume of a swimming pool?

The formula for calculating the volume of a swimming pool depends on its shape. Here are some common formulas:

1. Rectangular Pool: Volume = Length x Width x Depth
2. Circular Pool: Volume = π x (Diameter ÷ 2)² x Depth
3. Oval Pool: Volume = Length x Width x Average Depth x 0.89
4. Kidney-Shaped Pool: Volume = (Length + Width) ÷ 2 x Depth x 0.8

In these formulas, the length, width, and depth refer to the longest, widest, and deepest points of the pool. The diameter refers to the distance across the pool at its widest point, and the average depth is calculated by averaging the depth measurements taken at various points throughout the pool. π represents the mathematical constant pi (approximately equal to 3.14), and 0.89 and 0.8 are conversion factors used to adjust for the irregular shape of oval and kidney-shaped pools.
