In this lesson, we will learn about lateral surface area and how to calculate it for different geometric shapes.

Lateral surface area refers to the total surface area of an object excluding the top and bottom faces. It includes all the side faces of the object.

To calculate the lateral surface area of a shape, you need to find the sum of the areas of all the side faces. The formula for calculating lateral surface area varies depending on the shape.

For a rectangular prism, the lateral surface area can be calculated using the formula:

Lateral Surface Area = 2h(l + w)

Where h is the height of the prism, l is the length, and w is the width.

For a cylinder, the lateral surface area can be calculated using the formula:

Lateral Surface Area = 2πrh

Where r is the radius of the base and h is the height of the cylinder.

For a triangular prism, the lateral surface area can be calculated using the formula:

Lateral Surface Area = Ph

Where P is the perimeter of the base triangle and h is the height of the prism.

These formulas are used to calculate the lateral surface area of different geometric shapes. By understanding and applying these formulas, you can determine the lateral surface area of various objects.
