Introduction to Surface Area

Surface area is the total area of all faces of a three-dimensional object. Understanding surface area is important for packaging, painting, and material estimation.

For prisms, surface area includes the two bases plus all rectangular lateral faces. Calculating it accurately requires identifying all faces and their dimensions.

In this lesson, you'll learn to find the surface area of rectangular and triangular prisms.
