Lateral Area

Definition: Lateral Area is the sum of the surface areas of the faces excluding the base.

Formulas:

• Lateral surface area of a cube = 4b2
• Lateral surface area of a sphere = 4πr2
• Lateral surface area of a cone = π × r × s
• Lateral surface area of a cylinder = 2πrh
• Lateral surface area of the right triangular pyramid = 3 × area of lateral faces
• Lateral surface area of a pentagonal prism = 5 × area of each rectangle

b=base
r=radius
s=slant
h=height
π=pi
