Calculating Trapezoidal Prism Properties

This video tutorial explains how to calculate the volume and surface area of a trapezoidal prism. It begins with an introduction to the formulas used for these calculations. The video then provides a detailed walkthrough of calculating the volume by using the height of the trapezoid and the prism, as well as the lengths of the bases. Following this, the tutorial covers the two-step process for finding the surface area, which involves calculating the lateral area and the area of the two bases. The video concludes with a summary and information about the channel.
