Explanation Given Dimensions of the ceiling = 100 ft × 82 ft Thickness of the gold leaf = Five millionths of an inch = 5.0 × 10 − 6 in Density of gold = 19.32 g / cm 3 Cost of gold = $ 1654 per troy ounce 1 troy ounce = 31.1034768 g Formula The volume of the gold leaf is calculated using the formula, Volume ( V ) =l×b×h .....(1) Where, l is the length of the gold leaf. b is the breadth of the gold leaf. h is the height of the gold leaf. The conversion of 1 ft into centimeters ( cm ) is done as, 1 ft = 30.48 cm Hence, The conversion of 100 ft into centimeters ( cm ) is done as, 100 ft = ( 100 × 30.48 ) cm = 3048 cm This will be the length of the gold leaf required, that is "l" . The conversion of 82 ft into centimeters ( cm ) is done as, 82 ft = ( 82 × 30.48 ) cm = 2499 cm This will be the breadth of the gold leaf required, that is "b" . The given thickness of the gold leaf is the height of the gold leaf, that is "h" . Since, 1 in = 2 .54 cm Thus 5.0 × 10 − 6 in = 2 .54 × 5.0 × 10 − 6 cm = 1.27 × 10 − 5 cm Thus 5
