The video tutorial by Mr. J explains how to find the surface area of a rectangular pyramid. It begins with an introduction to the concept of surface area and the structure of a rectangular pyramid, which includes a base and four lateral triangular faces. The tutorial then demonstrates how to calculate the area of the base using the formula for a rectangle and the areas of the lateral faces using the formula for triangles. The video uses a net to visualize the pyramid's faces and organizes the calculated areas before summing them to find the total surface area. The final surface area is calculated to be 166.32 square meters.
