What Is Lateral Surface Area?

Lateral surface area refers to the area of all sides of a 3D shape excluding the top and bottom bases.

It is especially important when calculating:

• Material needed for wrapping
• Painting side walls
• Manufacturing cylindrical containers
• Architectural surface planning
