Volume and Surface Area of Right Prisms

This video tutorial focuses on the volume and surface area of right prisms. It explains how to calculate the surface area of polyhedrons by finding the area of each face and adding them up. The video also covers the volume of prisms and provides practical examples, such as determining the weight of a concrete bench using its volume and calculating the time to clean it using its surface area. The tutorial concludes with questions on using volume and surface area to calculate costs for materials like concrete and paint.
