Solution 57E: Here we have to calculate the cost of gold Step 1: Calculation the area of ceiling Given 2 Area of the ceiling = 100 ft * 82 ft = 8200 ft Step 2: Conversion the unit of ft to in. Area of the ceiling = 8200 ft 2 We know 1 ft =12 in Area of the ceiling = 8200 ft =8200 ft x ( 2 12 in) = 1180800 in 2 1 ft Step 3: calculation of the volume of the gold sheet Given, Thickness = five-millionths of an inch = 1/5x 10 in We know, 2 6 3 Volume = area x thickness= 1180800 in x 1/5x10 in = 0.23616 in Step 4: conversion the unit in3 to cm3 We know, 1 in =2.54 cm 3 2.54 cm 3 Volume of the sheet = 0.23616 in x ( 1 in ) = 3.869 cm 3
