Calculating Volume and Surface Area

The video tutorial explains how to calculate the surface area and volume of right prisms and cylinders. It presents a problem involving a triangular prism with a given volume and height, and demonstrates how to find the area of its base using the volume formula. The process involves substituting known values into the formula and solving for the unknown base area by dividing both sides of the equation. The tutorial concludes with the calculation of the base area as 15 cm squared.
