Question

A model of a car is made to scale of 1:10. What is the ratio of the volumes of the model car to the real car? If the model car has a mass of 2.1kg,what is the mass of the real car (assuming the same metal is used

Answer 1

The answer to your problem is:

1:1000 ( Ratio )

2,100 kg ( Weight )

Explanation:

The scale of 1:10 means a volume scale of 1:1000.

The ratio of the volumes is model:real = 1:1000.

Mass can be the proportional to the volume.

The real car has a volume 1000 times the volume of the model, so its mass is also 1000 times the mass of the car. Which then we need to multiply

= 1000 × 2.1 kg = 2100 kg

Thus the answer is:

1:1000 ( Ratio )

2,100 kg ( Weight )
