Question 837076
Let x = height of tower (in cm)


Drawing a picture will lead you to this proportion


150/6 = x/120


150*120 = 6x


18000 = 6x


6x = 18000


x = 18000/6


x = 3000


So the building is 3000 cm tall (or 3000/100 = 30 meters tall)


Note: 30 meters is roughly 98.4252 feet. So this is probably an 8 or 9 story building (each story is roughly 8-10 ft).
