Formulas For Surface Area of 3D Shapes.
TSA and CSATSA: Total Surface Area | CSA: Curved Surface Area |
CuboidSA = 2 x l x w + 2 x l x h + 2 x h x w | SA = Surface Area | l = Length | w = Width (Base) | h = Height |
CubeSA = 6a² | SA = Surface Area | a = 1 side |
| | CylinderSA = 2 x π x r x h + 2 x π x r² | SA = Surface Area | r = Radius | h = Height |
SphereSA = 4 x π x r² | r = Radius | SA = Surface Area |
HemisphereCSA = 2 x π x r²
CSA = Curved Surface Area
r = Radius |
TetrahedronSA = 4 x (π x r²)
SA = Surface Area
r = Radius |
| | Triangular PrismFor The Triangles = 2 x (b x h x 1/2) | For The Rectangles = 3 x (l x a) | b = Base(or Width) | a = 1 side (or c) | h = Height | l = Length |
ConeCSA = π x r x l
TSA = π x r x l + π x r²
TSA = Total Surface Area
CSA = Curved Surface Area
r = Radius
l = Length |
