Solution:-

From the question it is given that, a model of a ship is made to a scale of 1 : 200

(i) Given, the length of the model is 4 m

Then, length of the ship = (4 × 200)/1

= 800 m

(ii) Given, the area of the deck of the ship is 160000 m²

Then, area of deck of the model = 160000 × (1/200)²

= 160000 × (1/40000)

= 4 m²

(iii) Given, the volume of the model is 200 liters

Then, Volume of ship = 200 × (200/1)³

= 200 × 8000000

= (200 × 8000000)/100

= 1600000 m³
