Um einen 3 m hohen Schornstein zu streichen, werden 5,6 Liter Farbe benötigt. Was ist der höchste ähnliche Schornstein, der mit 8 Litern Farbe gestrichen werden kann?

Hello Guest!

$$(3m)^2:x^2=5.6l:8l\\ x^2=\frac{8l\cdot 9m^2}{5.6l}$$

$$x=3.586m$$

A 3.586m high chimney can be painted with 8l of paint.

3 m is to 5.6 l     as     x   is to 8 l

3 / 5.6  =  x / 8

3/5.6 * 8 = x = 4.29 m
