Question

The dimensions of a buiIding are 50 m Iong, 40m wide and 70m high. A model of the same building is made with a scale factor of 1: 500. Find the dimensions of the model.

Answer 1

Scale= 1 : 500 

1 cm  represents  500 cm

`500/100` = 5 m

1 cm represents 5 m 

Lengthof model = `50/5` = 10 cm

Breadth of model = `40/5` = 8 cm

Height of model =  `70/5` = 14 cm
