Ever wondered how much wrapping paper you’d need for a perfectly cubical present? Welcome to the wonderful world of cube surface area calculations! This is not a joke, it’s math. But hey, who says math can’t be fun?
The surface area of a cube is calculated using the formula:
Surface Area = 6 * (Edge Length)^2
Now, let’s get serious.
