Answer:
A = 2(lb + lh + bh)
Explanation:
To find the correct equation to use, we need to know the kind of shape the box is. Now, with the description given in the question, it can be seen that box is cuboidal in shape.
Hence, we need to know the surface area formula for a cuboid before we can know the equation to use
The surface area of a cuboid goes by the formula A = 2(lb + lh + bh)
This gives the formula to be used Where l, b and h are length, breadth and height respectively
