This tool calculates the total painting cost based on the area you provide and the price per square foot.

## How to Use the Painting Cost Calculator:

This calculator helps you estimate the cost of painting your walls based on the dimensions of the room, the paint coverage per gallon, and the number of coats you intend to apply.

### Instructions:

- Enter the length, width, and height of the room in feet. Ensure they are positive numbers.
- Provide the paint coverage in square feet per gallon as specified on the paint can.
- Enter the cost per gallon of paint.
- Specify the number of coats of paint you plan to apply. This must be at least 1.
- Click the “Calculate” button to see the results.

### Explanation of Calculations:

The calculator determines the total wall area by calculating the perimeter of the room (2 * length + 2 * width) and then multiplying by the height. It calculates the total area to be painted by considering the number of coats. The total gallons of paint required is determined by dividing this total area by the paint coverage per gallon. Lastly, the total paint cost is calculated by multiplying the gallons needed by the cost per gallon.

### Limitations:

This calculator assumes:

- The walls are smooth and do not have any windows or doors.
- Only rectangular rooms are considered, with four walls of the same height.
- The coverage and cost are consistent and represent average expected values.
