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 meters) of the Eiffel Tower.

Answer 1

Multiply 40.5 by 800
you get 32400
then divide by 100 to get to meters
324 meters

Answer 2

Hey,

The answer is: 324 m

Because:
1:800=1/800

So 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
