Answer #1

Volume = length * breadth * height

= 3.54*7.00*1.25

= 30.975 in3

1 in3 = 16.3871 cm3

30.975 in3 = 507.59 cm3

B. Mass = volume * density

= 507.59 * 19.32

= 9806.64 grams

In Troy ounce = 9806.64 / 31.10

= 315.326

Block value = 1291 * 315.326

= 407085.866 $

    There is a 10.0 grams necklace made of 18K gold. K, karat, is a measurement of the fineness (or purity) of gold by Jeweler and gold dealers. Compared with 24K (pure gold), 18K means that the mass percent of gold is = 0.75 (or 75 wt%, we treat it as an exact number here). In another word, that necklace contain 75% gold by mass. If the international gold price today is $1323 (US) per troy ounce, and one troy ounce...
