Tungsten is listed at less than 0.7 lb/cu in. That makes a 9 cu-in cube come in at less than 6.3 lbs. How can this cube weigh 17.6 lbs?

A cube 3 inches on a side has a volume of 27 cubic inches (3 in high x 3 in wide x 3 in deep), not 9 cubic inches. 18 g/cm^3 x 16.4 cm^3/in^3 x 27 in^3 = 7.97 kg or 17.5 lb.
