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

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
