What does the generator do?
The generator draws an unfolded net of a cuboid – 6 rectangles laid flat, each with dimensions (e.g. 5 × 3). Your task is to compute the total area of all rectangles, which is the cuboid surface area.
How to use it
The surface area of a cuboid is the sum of the areas of all 6 faces. In a cuboid the faces come in pairs (front = back, left = right, top = bottom). Formula: S = 2 · (a · b + a · c + b · c). Multiply each pair of dimensions, add them up, and double the result.
