## 209. Math Puzzle 10/82

A popular piece of exercise equipment in the gym is the rung ladder. The distance between the 22 rungs is $22 \mathrm{~cm}$ each, and the thickness of the rungs is $38 \mathrm{~mm}$.

How high can you climb if the bottom rung is $144 \mathrm{~mm}$ from the floor?
The height of the ladder is composed as follows:

$22 \cdot 38 \mathrm{~mm}+21 \cdot 220 \mathrm{~mm}+144 \mathrm{~mm}=5600 \mathrm{~mm}$.
