Answer:

200 square feet

Explanation:

The formula for the lateral surface area of a square pyramid is
a√(a^2+4h^2), where a is the side length and h is the height of the pyramid. The first step is therefore to find the height of the pyramid. Using the pythagorean theorem, you can find that it is
√(10^2-5^2)=5√(3). Plugging in our known values into the equation, you get
10\sqrt{10^2+4(5√(3))^2}=10√(100+300)=10\cdot 20=200. Hope this helps!
