Where:
Explanation: The formula calculates total paint needed by dividing the surface area by the coverage rate and multiplying by the number of coats.
Details: Accurate paint estimation helps prevent wastage, ensures you purchase the right amount of paint, and helps with budget planning for exterior painting projects.
Tips: Measure the total exterior surface area accurately, check the paint manufacturer's coverage specifications, and consider the number of coats needed for proper coverage. All values must be positive numbers.
