Worked Solution
Step 1: Identify the dimensions of the rectangular container and water level.
Base: 40 cm × 25 cm; Water height: 18 cm
Step 2: Calculate the volume of water in cubic centimetres.
Volume = length × width × height
Volume = 40 × 25 × 18 = 18,000 cm³
Step 3: Convert cubic centimetres to litres.
18,000 cm³ ÷ 1,000 = 18 litres
Final answer: 18 litres
Correct answer: 18 litres
