If it is a Square pyramid, you’ll need to find the area of your base + the 4 triangular sides of the pyramid . If s=14 on one side, then you can find the base of your pyramid by doing 14^2. To find the triangles, you do (14 x 13)/2 x 4, or do (14 x 13) x 2. Once you find the area of all the surfaces, add them all together to get your total surface area.
