<p>A trapezoidal prism consists of two trapezoidal bases and four rectangular lateral surfaces. The lateral surface area represents the sum of the areas of these four rectangular faces. Let's take an example of a tent, which resembles a trapezoidal prism. The fabric covering the sides of the tent forms the lateral surfaces, while the top and bottom trapezoidal parts are not included as they are the bases.</p>
