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?
360 m2
320 m2
260 m2
120 m2

Answer 1

4*1/2*slant height*base + base * base

Answer 2

so confused

Answer 3

The surface area of a regular pyramid is equal to the area of its base plus 1/2 times the perimeter of its base times the slant height.
SA = 10*10 + (1/2)*(40)(13)
SA = 100 + 260
SA = 360 square meters
