#### Answer

Kangchenjunga is taller by 70 meters.

#### Work Step by Step

We can convert the height of Kangchenjunga from units of feet to units of centimeters.
$28,170~ft = \frac{28,170~ft}{1}\times \frac{12~in}{1~ft} \times \frac{2.54~cm}{1~in} = 858600~cm$
Since 1 m = 100 cm, we need to move the decimal place 2 places to the left to convert from units of cm to units of m.
$858600~cm = 8586~m$
Kangchenjunga has a height of 8586 m.
Lhotse has a height of 8516 m.
