Calculating Volume and Surface Area

The video tutorial explains how to calculate the volume of a prism when the volume is given. It starts by introducing the volume formula for prisms, which is the base area multiplied by the height. The tutorial then focuses on calculating the base area of a polygon, using a specific formula involving the number of sides and the length of a side. The instructor demonstrates how to solve for unknown values in the formula, such as the length of a side, and completes the calculations to find the missing dimensions of the prism. The tutorial concludes with a practice exercise to reinforce the concepts learned.
