Answer:

approx 216

Explanation:

well we go to the 10mm mark and we add the columns taht appear before that. Those are two columns : the brown/orangey one and the green one.

if the scale goes up in twenty and each jump has four squares then we can say that one square is equal to 5 up

so we now can read the first two columns

the first one reads 135

the second one reads approximately 81

we add those up and that becomes 216

so the answer is approximately 216
