How many nickels would could be stacked up reach the height of mt. everest? a nickel is 1.95 mm thick, and mt. everest is 29,029 m tall. using dimensional analysis.

you

14,866,667 nickels

Explanation:

10mm= 1cm

100cm= 1m

1000mm= 1m  or 1mm= 0.001m

20,029 m= 20,029*1000 mm=29,029,000mm

Dividing the height of the Mt. Everest by the thickness of nickel= 29,029,000/1.95=14,886,666.667

or 14,866,667 nickels
