Worked Solution

Step 1: Volume of the tank = Length × Breadth × Height Step 2: Volume = 20 cm × 15 cm × 10 cm = 3000 cm³. Step 3: Since it is filled to half its height, the volume of water is half of the tank's volume. Step 4: Volume of water = 3000 cm³ ÷ 2 = 1500 cm³. Answer: 1500

Correct answer: 1500
