Calculation of the lateral surface area of a right triangular pyramid

To find the lateral surface area of a right triangular pyramid, we need to know the slant height and the base length of the triangle.

Given information: - The lateral faces of the pyramid are inclined to the base plane at an angle of 60 degrees. - The distance from the center of the base to a lateral face is 2 cm.

To calculate the lateral surface area, we can use the formula:

Lateral Surface Area = (1/2) * Perimeter of the Base * Slant Height

Let's break down the steps to find the lateral surface area:

Step 1: Finding the base length of the triangle

Unfortunately, the base length of the triangle is not provided in the given information. Therefore, we cannot calculate the lateral surface area without this information.

If you have the base length of the triangle, please provide it, and I will be happy to help you calculate the lateral surface area of the pyramid.
