3-D Formulas

• Cube

• Surface Area of Cube = 6a2
• Volume of Cube = a3

Where 
‘a’ is the length of sides of Cube

• Cylinder

• Curved Surface Area of Cylinder = 2πrh
• Total Surface Area of Cylinder = 2πr(r + h)
• Volume of Cylinder = V = πr2h

Where 
‘r’ is the radius of base of Cylinder
‘h’ is the height of Cylinder

• Cone

• Curved Surface Area of Cone = πrl
• Total Surface Area of Cone = πr(r + l) = πr[r + √(h2 + r2)]
• Volume of Cone = V = 1/3× πr2h

where, 
‘r’ is the Radius of base of Cone
h is the Height of the Cone

• Sphere

1. Surface Area of a Sphere = S = 4πr2
2. Volume of a Sphere = V = 4/3 × πr3

Where, 
r is the Radius of Sphere
