Easily determine the lateral surface area (LSA) of various 3D shapes like cylinders, cones, prisms, and pyramids with our free online calculator. Understand the difference between total and lateral surface area and streamline your geometry calculations for academic or practical applications.
Formula:
The Lateral Surface Area (LSA) of a three-dimensional object is the area of all the sides of the object, excluding the area of its base(s). It measures the area of the "walls" of a shape.
- Cylinder: LSA = 2πrh
- Cone: LSA = πr√(r2 + h2)
- Rectangular Prism: LSA = 2h(l + w)
- Square Pyramid: LSA = 2a√( (a/2)2 + h2)
Where:
- r = radius
- h = height
- l = length
- w = width
- a = base side length
