Bob has a cube of silver that measures 3 inches on each side. A cubic inch of silver weighs 6 ounces. Each ounce of silver sells for $25. He sells it for 110% of its silver value. How much does he sell it for?

The silver has a volume of 3 * 3 * 3 = 27 cubic inches. So it weighs 27 * 6 = 162 ounces. So its value is 162 * 25 = $4050. That means he sold it for 4050 * 1.1 = $4455.
Thus, the answer is 4455.
