Question

Your grandparents bring you a 1:800 scale model of the Eiffel Tower after a trip to Paris. The height of the model is 40.5 centimeters. Find the actual height x (in centimeters) of the Eiffel Tower.

Answer 1

1:800=1/800
We have the following equation:
1/800=40.5 cm/x
x=40.5 cm (800)=32,400 cm

32,400 cm=32,400 cm(1 m/100 cm)=324 m

answer: The actual heigth of the Eiffel tower would be 324 m.
