The Inflatable Calculator helps determine the required volume of air needed to fully inflate an inflatable object, such as a pool, bounce house, or balloon. This calculator is useful for event planners, pool owners, and hobbyists.

## Inputs:

**Diameter (D)**: The diameter of the inflatable (in meters or feet).**Height (H)**: The height of the inflatable (in meters or feet).**Shape of the Inflatable**: The geometric shape of the inflatable (e.g., sphere, cylinder, rectangular prism).

## Formulas and Calculations:

## Volume Calculation:

The formula to calculate the volume depends on the shape of the inflatable.

**Sphere**:

- The formula to calculate the volume of a sphere is:

[ V = \frac{4}{3} \pi \left( \frac{D}{2} \right)^3 ]

**Cylinder**:

- The formula to calculate the volume of a cylinder is:

[ V = \pi \left( \frac{D}{2} \right)^2 H ]

**Rectangular Prism**(for inflatables with length (L), width (W), and height (H)):

- The formula to calculate the volume of a rectangular prism is:

[ V = L \times W \times H ]

## Example Calculations:

**Inputs**:

- Diameter (D): 3 meters
- Height (H): 2 meters (for cylindrical inflatables)
- Shape: Sphere and Cylinder

## Step-by-Step Calculation:

**For a Sphere**:

- Using the formula:

[ V = \frac{4}{3} \pi \left( \frac{3}{2} \right)^3 ] - Simplifying:

[ V = \frac{4}{3} \pi \left( 1.5 \right)^3 = \frac{4}{3} \pi \times 3.375 = 14.137 \, \text{m}^3 ]

**For a Cylinder**:

- Using the formula:

[ V = \pi \left( \frac{3}{2} \right)^2 \times 2 ] - Simplifying:

[ V = \pi \times 2.25 \times 2 = \pi \times 4.5 = 14.137 \, \text{m}^3 ]

## Summary:

For a sphere with a diameter of 3 meters, the required volume of air is approximately 14.137 cubic meters. For a cylinder with a diameter of 3 meters and a height of 2 meters, the required volume of air is also approximately 14.137 cubic meters.

## Conclusion

The Inflatable Calculator is a valuable tool for event planners, pool owners, and hobbyists, providing a quick and accurate way to determine the required volume of air for various inflatable objects. By inputting the diameter, height, and shape of the inflatable, users can easily calculate the necessary air volume, helping them plan and execute their events efficiently.
