. Therefore a case of cans with a radius equal to 1 inch would cost about
$2.26 to produce, and a case of cans with a radius equal to 2 inches would cost
about $5.42. (See Surface Area.)
Temperature usually changes according to changes in elevation. In fact, the
boiling point of water in degrees Celsius, 
b, can approximate the elevation above
sea level in meters, 
e, according to the equation e = 1000(100 − b)

+
580(100 − b). This means that water will boil at 100° Celsius near sea level, and
closer to 99° Celsius at about one mile in altitude, such as near Denver,
Colorado.
