**The missing image is attached below**

The correct answer is: 400 ft^3

Explanation:
The volume of the square pyramid = [tex]\frac{a^2h }{3} [/tex]

Where a = base  = 10 ft
h = [tex] \sqrt{x^2 - ( \frac{a}{2} )^2} = \sqrt{13^2 - 5^2} = \sqrt{144} = 12 [/tex]

Plug in the values in the equation:
The volume of the square pyramid = [tex]\frac{10^212 }{3} [/tex] = 400 ft^3
