The bottom of a shopping bag measures 8 inches by 10 inches. The bag height of 12 inches. How much paper is needed to make the bad?

8 * 10 = ?

2(8 * 12) = ?
2(10 * 12) = ?

Add the three products together.

For an open-top rectangular prism with width w, length L and height h,

the area of the base is wL.
The area of the 4 sides is
2h(w+L)
So the surface area of the open prism/bag is
A=wL+2h(w+L).
The correct answer is one of the given choices.

512 square inches is correct.
