So this does weigh approximately 1 lb, 454 grams, but the listed dimensions do not make sense for a trapezoidal prism nor does it have a dimension 1.8 inches (4.572 cm) anywhere. It has a length of 7.99 cm, height of 2 cm, top width of 2.5 cm, bottom width of 3.4 cm. Using the equation to find volume of trapezoidal prism 1/2(a + b)*h*l where 'a' is the top width, 'b' is the bottom width, 'h' is the height of trapezoid and 'l' is the length of the prism. Using the dimensions mentioned before, we get a volume of 47.082 cm^3. The density of copper is 8.96 g/cm^3. (47.082 cm^3 * 8.96 g/cm^3), the cm^3 cancel, you get 421.85 grams of copper. Like i mentioned before, this does weigh 1 lb (454 grams), but there isn't 454 grams of copper, there's at most 421.85 grams. (421.85 g/ 424 g) * 100 = 92.919%. So, if this made from 421.85 grams copper it certainly isn't 99.9% pure. AT MOST has a 92.919% purity, but now i'm skeptical about the product and I will be returning it. Its either copper plated or some sort of copper alloy, i'm not sure, but I am sure that you shouldn't buy it because you will get scammed. Take care, but not to these people.
