What is Surface Area? 🤔
**Surface Area (SA)** is the total area of all the faces, or surfaces, of a three-dimensional object. It's like finding the amount of wrapping paper needed to cover a box.
To find the surface area of a shape, you first need to identify all of its faces and then calculate the area of each one. Then you just add up all the areas!
