Question

A square pyramid has a slant height of 13 meters and a height of 12 meters. What is the surface area if the square base has sides of length 10 meters?
Answer
120 m2
260 m2
320 m2
360 m2

Answer 1

Surface area of base = 10 * 10 = 100m2
Surface area of four sides = 0.5 * 10 * 13 * 4 = 260 m2
Hence total = 360 m2
