Find the height or length of these of these natural wonders in kilometers , meters , and centimeters .

(a)The longest cave system in the world is the Mammoth Cave system in Central Kentucky. It has a mapped length of 384 miles
(b)In the United States , the waterfall with the greatest single drop is Ribbon Falls in California which drops 1 612 ft
(c)Mount McKinley in Alaska is America's highest mountain at 20 320 feet
(d)The deepest canyon in the United States is King's Canyon in California with a depth of 8 200 ft.
-------------------------------

a) we have 384 miles as the lenth of cave
As we know 1 mi = 1609 m
then 384 X 1609 m
= 559.93
now we change to kilometers , meters , and centimeters .

559.93 X 1000 m
= 559930
559930 X 100 cm
=55993000 cm
------
(b)

1 ft = 0.3048 m
1 612 ft = 1 612 X 0.3048
=491.3376
491.3376 x 1000 m
4913376
4913376 X 100 cm
4913376

(c) and ( d) i try later

then 384 X 1609 m = 617,856 m
= 559.93 <<<<<<<< unfortunately wrong

(b)

1 ft = 0.3048 m
1 612 ft = 1 612 X 0.3048 m
=491.3376 m
491.3376 x 1000 mm/m
491,337.6 mm
