The document defines total surface area and provides formulas to calculate the total surface area of various solid shapes, including cubes, cuboids, cylinders, cones, and pyramids. It states that total surface area is the sum of the surface areas of all faces of an object. Formulas are given as total surface area of a cube = 6s^2, total surface area of a cuboid = 2(LxW) + 2(LW) + 2(LW), and total surface area of a cone = πrs + πr^2, where r is the radius and s is the slant height.
