This document provides formulas for calculating the lateral surface area of various 3D shapes. It states that the lateral surface area of any prism is equal to the perimeter of its base multiplied by its height. Formulas are given for triangular prisms as (a+b+c) x h, rectangular prisms as (a+b+c+d) x h, cubes as 4axa, and cylinders as 2Πrh, where a, b, c, d are base side lengths, h is the height, r is the radius, and Π is pi.
