Math Formulas For Surface Area Of 3D Shapes Cheat Sheet by

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
