A model of a ship is made to a scale of 1:160 find the length of the ship if the length of its model is 1.2m, tthe area of deck of the ship if the area of deck of its model is 1.2m square,the volume of the ship if the volume of its model is 1.2m cube

The scale factor=k=1/160

1.Length of model=k*length of ship
1.2=1/160*length of ship

Therefore,length of ship=160*1.2=192

2.Area of the deck of model=k^2*area of deck of ship
1.2m^2=k^2*area of deck of ship
Therefore,area of deck of ship=1.2*160^2=30,720m^2

3.volume of model=k^3*volume of ship
Therefore,volume of ship=1.2m^3*160^3
=49,15,200m^3

LENGTH = length * scale factor

AREA = area * (scale factor)^2

VOLUME = volume * (scale factor)^3

To find the length of the ship, you need to scale up the length of its model using the given scale factor.

Scale factor = 1 : 160

Length of the model = 1.2m

Length of the ship = Length of the model * Scale factor
= 1.2m * 160
= 192m

Therefore, the length of the ship is 192 meters.

To find the area of the deck of the ship, you need to scale up the area of the deck of its model using the given scale factor.

Scale factor = 1 : 160

Area of the model's deck = 1.2 square meters

Area of the ship's deck = Area of the model's deck * (Scale factor)^2
= 1.2m^2 * (160^2)
= 1.2m^2 * 25600
= 30720 square meters

Therefore, the area of the deck of the ship is 30720 square meters.

To find the volume of the ship, you need to scale up the volume of its model using the given scale factor.

Scale factor = 1 : 160

Volume of the model = 1.2 cubic meters

Volume of the ship = Volume of the model * (Scale factor)^3
= 1.2m^3 * (160^3)
= 1.2m^3 * 4096000
= 4915200 cubic meters

Therefore, the volume of the ship is 4915200 cubic meters.

A model boat is made on a scale of 1 : 128. If the boat model has a length of 30 cm, what is the length of the actual boat?
