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

These are the triangle sides of the pyramid.
The area is 13*10/2=65
There are 4 of these: 4*65=260 and the square base 10*10=100
So the answer is 360 m^2
