Geometry

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

Key Concept Explanation:
Volume = (1/3) × base area × height
Base area = side × side

Step-by-Step Solution:
Base area = 16 × 16 = 256 cm²
Volume = (1/3) × 256 × 15 = 3840 × (1/3) = 1280 cm³

Common Mistakes:
Forgetting to divide by 3 or calculating base incorrectly

Summary:
Square base means squaring the side before using volume formula...
