Help, please !?What is the lateral area of the pyramid shown below?

Question

Answer 1

If you put a plane down the center of the pyramid like this:

You would get a triangle in the center that would be a right triangle and you could use the Pythagorean Theorem to solve for the height (x). It would be the square root of 26² - 10² or x would be 24.

From that, you can use the regular volume equation for a right pyramid, V = 1/3Bh where V = volume, B = area of the base, and h = height.

V = 1/3(20)(20)(24) = 3200 cu ft
