A Correct answer
Explanation

The lateral surface area of a cuboid is the sum of the areas of the four vertical faces, which is 2 * height * (length + breadth).

AI explanation

The lateral surface area of a cuboid is the area of its four vertical faces, calculated as length times height plus breadth times height, all multiplied by two. This gives the formula $2(lh + bh)$, which factors out the height to become $2(l+b)h$. The lateral surface area is $2(l+b)h$.
