total surface area is all of the area. ex. for a square pyramid it would be the area of the square on the bottom and the four triangle sides lateral surface area is all the surface area EXCEPT the base. ex. for a square pyramid it would be the area of the four sides of the pyramid. the bottom square is NOT included. for a triangular prism it would be the area of the three rectangle sides, NOT the two triangular sides

The lateral area of a prism is the sum of the areas of all the lateral faces. A lateral face is not a base. The surface area is the total area of all faces.Lateral Area: The lateral area of a right prism with base perimeter P and height h is L=Ph.Surface Area: The surface area of a right prism with lateral area L and base area is B is S = L + 2B, or S = Ph + 2B.
The total surface area is 1,105.84 units2The lateral surface area is 703.72 units2
The lateral area of a right cylinder is curved surface that connects the two bases. The surface area is the total area of the curved surface and the bases.Lateral Area: The lateral area of a right cylinder with radius r and height h is L = 2pirh.Surface Area: The surface area of a right cylinder with lateral area L and base area B is S = L + 2B, or S = 2pirh + 2pir^2.
To calculate the surface area of a cylinder, you need to add the areas of the two bases (top and bottom) and the lateral surface area. The formula for the lateral surface area of a cylinder is 2πrh, where r is the radius and h is the height. Given the radius is 7cm (half of the diameter) and the height is 18cm, the lateral surface area is 2 * π * 7 * 18 = 252π cm². The total surface area is the sum of the lateral surface area and the areas of the two bases, which is 252π + 2(πr²) = 252π + 2(π*7²) = 252π + 98π = 350π cm², or approximately 1099.65 cm².
Curved surface area of a hemisphere means only the bent part of it , i.e,the part which looks like half of a sphere. Total surface area of a hemisphere is the circular top of a hemisphere + curved surface area of a hemisphere. So the formula goes like this: Curved surface area of hemisphere= 2πr2 Total surface area of hemisphere= 2πr2 + πr2 = 3πr2
