Trapezoidal Prism Surface Area and Volume

The video tutorial explains how to find the surface area and volume of a trapezoidal prism. It begins with an introduction to the properties of a trapezoidal prism, followed by detailed steps to draw its net. The tutorial then covers the calculation of the surface area by multiplying the length and width of each rectangle in the lateral area and finding the area of the base. Finally, it explains how to calculate the volume by multiplying the area of the base by the height of the prism.
