Geometry

Question Analysis:
This is a volume problem involving a square-based pyramid.

Key Concept Explanation:
Square base area = side × side; volume = (1/3) × base area × height

Step-by-Step Solution:
Base area = 12 × 12 = 144 cm²
Volume = (1/3) × 144 × 10 = 1440 × (1/3) = 480 cm³

Common Mistakes:
Not dividing by 3; using wrong formula

Summary:
Calculate base area first, then apply the pyramid volume formula.
