Find the height or length of these natural wonders in km, m, and cm. A. A cave system with a mapped length of 354 miles. B. A waterfall that drops 1,235.2 ft. C. A 21320 ft tall mountain. D. A canyon with a depth of 6630 ft.

Explanation:

Some standard unit conversion are 1 mile = 1.609344 km, 1 ft.= 30.48 cm,

1 km= 1000 m or 1 m = 0.001 km and 1 m= 100 cm or 1 cm=0.01 m.

Now, use these values to convert the given lengths.

A. length of cave = 5 miles (given)

From standard value 1 mile = 1.609344 km

5 miles = 1.609344 km= 8.04672 km,

5 miles =8.04672 1000 m= 8046.72 m [ as 1 km = 1000 m]

5 miles = 8046.72 100 cm=804672 cm

B. Height of the waterfall = 1235 ft. (given)

1 ft.= 30.48 cm [ from standard value]

1235.2 ft.= 1235.2 30.48 cm=37648.896 cm,

1235.2 ft.=37648.896 0.01 m =376.48896 m [ as 1 cm = 0.01 m]

1235.2 ft.=376.48896 0.001 km =0.37648896 km [ as 1 m = 0.001 km]

C. Height of the mountain= 21320 ft. (given)

From standard value: 1 ft.= 30.48 cm

21320 ft.= 21320 30.48 cm=649833.6 cm,

21320 ft.=649833.6 0.01 m =6498.336 m [ as 1 cm = 0.01 m]

21320 ft.=6498.336 0.001 km =6.498336 km [ as 1 m = 0.001 km].

D. Depth of canyon =6630 ft.

From standard value: 1 ft.= 30.48 cm

6630 ft.= 6630 30.48 cm=202082.4 cm,

6630 ft.=202082.4   0.01 m =2020.824  m [ as 1 cm = 0.01 m]

6630 ft.=2020.824   0.001 km =2.020824  km [ as 1 m = 0.001 km].
