You did not provide enough information. The answer depends upon the shape.
If this is a rectangular box where the long side is 10", assuming the base is square, the sides of the base would be sqrt 6. So you would have a box that is sqrt6 x sqrt 6 x 10. The surface area of the box is 40x sqrt 6 + the top and bottom, 12, which is about 110 sq inches, and the perimeter of the base is 4 x sqrt 6 = 12.
I did not try other shapes such as a square pyramid, 3d trapezoid, etc.
You need more information.
