In math class, Abby learned that the ratio between the surface area of a cube and the area of one side is 6 to 1. When Abby got a cube-shaped box in the mail, she decided to test this fact. The area of one side of the box was 20 square inches.

What was the surface area of the entire box?

If the ratio between the surface area of a cube and the area of one side is 6 to 1, then the surface area of the entire box is 6 * 20 = <<6*20=120>>120 square inches. Answer: \boxed{120}.
