You can put this solution on YOUR website!
I assume she's just covering the outside
of the box
9 x 4 is the bottom pf the box
There are 2 opposite sides that are:
3 x 4
There are 2 opposite sides that are:
3 x 9
------------
+9%2A4+%2B+2%2A3%2A4+%2B+2%2A3%2A9+
+36+%2B+24+%2B+54+=+114+
She needs 114 square inches of wrapping paper
