Question

A train is 200m long.A model of the train is made which is 80cm long.Find [ (a) ( the length of the model )/( the length of the model ), (b) the surface area of the model (c) the volume of the train the volume of the model​

Answer 1

a) length of the train = 200m =20000cm

length of the model train = 80cm

the length of the model / the length of the train

= 20000 ÷ 80

= 250

the ratio of the length of the trail and the model is 1:250

(b) the surface area of the model.

The breadth ( width) of the model is not given.

(c) The volume of the train and the volume of the model.

Neither the breadth of the train nor the breadth of the model has been given. So, the volume cannot be calculated.
