What is Meant by Surface Area?

In Mathematics, the surface area is the total area of the surface of a three-dimensional object. It is a measure of the extent of the surface and is typically expressed in square units. The surface area calculation helps in understanding how much area is covered by the surface of an object. Below are the formulas to calculate the surface area for common shapes:

• Cube: SA = 6 × side²
• Rectangular Prism: SA = 2 × (length × width + length × height + width × height)
• Sphere: SA = 4 × π × radius²
