Formulas For Surface Area of 3D Shapes.
TSA and CSA
TSA: Total Surface Area |
CSA: Curved Surface Area |
Cuboid
SA = 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 |
Cube
SA = 6a² |
SA = Surface Area |
a = 1 side |
|
|
Cylinder
SA = 2 x π x r x h + 2 x π x r² |
SA = Surface Area |
r = Radius |
h = Height |
Sphere
SA = 4 x π x r² |
r = Radius |
SA = Surface Area |
Hemisphere
CSA = 2 x π x r²
CSA = Curved Surface Area
r = Radius |
Tetrahedron
SA = 4 x (π x r²)
SA = Surface Area
r = Radius |
|
|
Triangular Prism
For 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 |
Cone
CSA = 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 |
