How is the volume of an oval-shaped pool calculated in gallons?

The volume of an oval-shaped pool is calculated using the formula that takes into account the shape of the pool. An oval pool can be approximated as an ellipse when calculating volume. The formula for the volume in gallons often involves a specific multiplier to convert the cubic dimensions into gallons.

In this case, the volume is calculated as Length multiplied by Width multiplied by a factor that serves as a conversion constant based on the average depth and the shape of the pool. The factor 6.7 is used to convert the dimensions (typically in feet) into gallons, reflecting how the pool's dimensions correlate with its actual volume.

This formula thus provides a practical method for pool operators to estimate the water capacity of an oval or elliptical-shaped pool effectively. The other options either lack the multiplier necessary for converting the volume into gallons or do not account correctly for the pool's dimensions, making them unsuitable for this calculation.
