Battleship Measurement Challenge

The fleet is preparing to leave harbour. Solve each measurement challenge, show your working where useful, and include units in your answers.

Harbour measurements

Use the fleet information panel for Questions 1–4.

Ship A Length: 150 m Deck: 30 m × 10 m Anchor chain: 45.7 m

Ship B Length: 1.8 km Cargo container: 3 m × 2 m × 2 m Fuel tank: 5,000 L; fuel aboard: 1,250 L

1.Ship A is 150 m long. How many centimetres is this?

2.Calculate the area of Ship A’s rectangular deck. Include the correct square unit.

3.Round Ship A’s 45.7 m anchor chain length to the nearest metre.

4.Which unit is most suitable for recording the height of a battleship: millimetres, metres or kilometres? Explain briefly.

Cargo and navigation

Use your knowledge of length, area, volume and capacity to keep the fleet on course.

5.Find the volume of Ship B’s container: 3 m long, 2 m wide and 2 m high. Show the calculation and give the unit.

6.If the container holds 12 m³ of water when full, how many litres is that? Use 1 m³ = 1,000 L.

7.A submarine travels once around a square naval base. Each side is 2.5 km long. What total distance does it travel?

8.Ship B is 1.8 km long. Convert its length to metres, then say how much longer it is than Ship A.

9.Ship B’s tank holds 5,000 L. It has 1,250 L aboard. How many more litres are needed to fill the tank?

10.A lifeboat carries 850 L of water. Convert this amount to millilitres.

Captain’s design challenge

Plan a safe landing place and check the fleet’s travel distance.

11.Choose whole-number dimensions for a rectangular helicopter landing pad with an area of exactly 24 m². Give one possible length and width, and check your answer.

Draw a rectangle and label its length and width. Make the labels match your answer to Question 11.

12.The ship travels 2.5 km in 10 minutes at a steady speed. How far will it travel in 60 minutes?
