Cube = 6a²
Rectangular Prism  = 2ab + 2bc + 2ac
Sphere = 4 \pi
Cylinder = 2  \pi r² + 2 \pi rh

surface area is the sum of all the areas of all the shapes that cover the surface. pls don't forget the pi= 3.141592. Surface Area of a Cylinder = 2 pi r 2 + 2 pi r h. Surface Area of a Sphere = 4 pi r 2. surface area of any prism : Surface Area = Lateral area + Area of two ends

(Lateral area) = (perimeter of shape b) * L

Surface Area = (perimeter of shape b) * L+ 2*(Area of shape b)
