Drawing the net, we see that is composed of 6 rectangles.

  • Two of these rectangles have dimensions of 13 cm by 21 cm. The combined area of these rectangles is 546 square cm.
  • Two of these rectangles have dimensions of 3.5 cm by 21 cm. The combined area of these rectangles is 147 square cm.
  • Two of these rectangles have dimensions of 3.5 cm by 13 cm. The combined area of these rectangles is 91 square cm.

Adding, we get
546+147+91=784
