3) A model car has a volume of 20 cubic cm. The scale of the model is 1:800000. Work out the
volume of the car of the real plane. Give your answer in cubic metres.
Ok this is quite simple once you gotten the concept. 1:800000 is the ration. The 1 will become 20 so the other side must be multiplied by 20 as well. so the new ratio is 20: 16,000,000.
