Question 207607: A toy manufacturer produces model cars which are similar in every way to the actual cars. If the ratio of the door area of the model to the door area of the car is 1:2500, find

You can put this solution on YOUR website!
First find the linear scale.
You are told two areas are scaled at 1:2500
You know area is measured in squared linear dimension.
SO, what is the sqaureroot of 2500?
sqrt%282500%29+=+50
Thus the linear scale is 1:50
Now, you are asked about 'capacity of the petrol tanks'. That is a volume. And volume are in cubic dimensions.
So the scale needs to be cubed
1%5E3%3A50%5E3
1%3A125000
wow
