A pyramid-shaped tent has a square base with a side of 10 m and a slant height of 6 m. If the base is also covered, what is the total area of canvas needed?
Show answer & explanation
Correct answer: B
Explanation
Given:
Base side = 10 m
Slant length = 6 m
Formula:
Curved surface area of a square pyramid = 2al
Base area = a²
Curved surface area = 2 × 10 × 6 = 120
Base area = 10² = 100
Total canvas area = 120 + 100 = 220
Total canvas area = 220 m²
