The document discusses formulas for calculating the surface area of various shapes. It provides the formulas to calculate the surface area of bases (A=πr^2) and curved surfaces (C=πd) of objects. It then shows how to calculate the total surface area (S) by adding the surface areas of the bases and curved surface.
