The surface area of an oblique cylinder is the sum of the areas of all its surfaces. An oblique cylinder is a cylinder where the top and bottom circles are not parallel to each other, and its sides are curved rectangles. To find the surface area of an oblique cylinder, you need to calculate the area of each surface separately and then add them together.

Real-life examples of oblique cylinders include soda cans and many types of industrial tanks and storage containers that are tilted or positioned at an angle. The surface area of an oblique cylinder is important to know in industries such as manufacturing and engineering, where these shapes are commonly used in the design and production of products and equipment.

The formula for determining the surface area of an oblique cylinder is defined as:
