Paint surface area calculation.
Triangular surface:
To find the squares of a triangular surface, multiply the height by the width and divide what you find by 2.
Square or Rectangular Surface:
To find the squares of a square or rectangular area multiply the length by the height.
Cylindrical Surface:
To find the squares of a cylindrical surface when the perimeter of the circle of the base is known, multiply the perimeter of the circle by the height. When the diameter is known multiply the diameter by 3.1416 and the result gives the circumference of the circle. Then multiply the perimeter of the circle by the height.
Circular Surface:
To find the area of a circle, multiply the diameter with itself and then by 0.7854.
If you do not know the diameter, but only the radius of the circle, then multiply the radius by itself and then by 3.14.
If you do not know the diameter, but only the radius of the circle, then multiply the radius by itself and then by 3.14.
Spherical Surface:
We Find the squares of a spherical surface by multiplying its diameter with itself and then what we found by 3.1416.
If we do not have the diameter we can find it by measuring the perimeter of the circle and multiplying it by 0.31831.
If we do not have the diameter we can find it by measuring the perimeter of the circle and multiplying it by 0.31831.
Conical Surface:
To find the area of the total surface of the cone, it is enough to add the area of its base (EB) to the area of the adjacent surface (EP).
Where π = 3.14
Where π = 3.14
Corrugated metal surface:
Metal sheet 2 ½. To find the width of the sheet before it becomes corrugated, multiply the width of the corrugated sheet by 1.08.
Metal sheet 1 ¼. To find the width of the sheet we multiply the width of the corrugated sheet by 1.11.
Metal sheet 1 ¼. To find the width of the sheet we multiply the width of the corrugated sheet by 1.11.

Fences:
When applying the paint with a spray gun, consider that it is a single surface, due to the loss of paint that exists. Double the amount of paint to cover both sides. To calculate how much paint is needed you must first decide the method of application. The most economical method is to apply paint with a wide roller.
