From a 10inchby19inch piece of cardboard, 3inchsquare corners are cut out, as shown in the figure above, and the resulting flaps are folded up to form an open box.
Find the surface area and volume of the open box

Math

With 3 inches cut from each corner, the dimensions would be (106) by (196).
V = 4 * 13 * 3 = ?
If it is the surface area within the box, in other words, the bottom, 4 * 13 = ?
