Luther bought a snack pack of crackers, and he thinks it's interesting that the cylindrical tower of crackers came in a box shaped like a square prism. He wonders how much extra space the box contains around the cracker tower. The box has a height of 8 inches and a side length of 2 inches. If the stack of crackers has a height of 7.9 inches and a diameter of 1.9 inches, what is the volume of the extra space in the box?

Round your answer to the nearest tenth.
