Worked Solution

Step 1: Write the volume formula for a cuboid. V = length × width × height. Step 2: Substitute what is known. 240 = 10 × 6 × height. Step 3: Find the base area first (length × width). Base area = 10 × 6 = 60 cm². Step 4: Divide volume by base area to find the height. Height = 240 ÷ 60 = 4 cm. Check (reverse): 10 × 6 × 4 = 60 × 4 = 240 cm³ ✓ Final answer: The height is 4 cm. Answer: 4 cm

Correct answer: 4 cm
