The height of a pyramid is 8 m, and the base of the pyramid is a square whose diagonal is m. Find the approximate volume of the pyramid.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 683 m3.
Diagonal of square base = √512 = 16√2 m
Each side of the square base = (16√2)/√2 = 16 m
Area of base = 162 = 256 m2
Height = 8 m
Volume of pyramid = (1/3) × Base area × Height = (1/3) × 256 × 8 = 2048/3 ≈ 683 m3
