Answer 2

380

Explanation:

The surface of a square pyramid is made up of a single square in the center, and four triangles on the sides. The square's area is 10*10=100, while the area of each of the triangles is 10*14/2=70. Multiplying this by the 4 triangles, you get 280. Adding them together, you get a total of 380 square meters. Hope this helps!
