Answer:

3200 cm^3

Step-by-step explanation:

1. Calculate the sides of the right triangle to get the height

We know that side c = 26 and the shortest leg is 10 cm (20cm/2) because this right triangle splits the 20cm in two)

10^{2} + b^{2} = 26^{2}   \\100 + b^{2} = 676\\b^{2} = 576 \\b = \sqrt{576} \\b = 24

a = 10, b = 24, c = 26

2. Use the formula for the volume of a square pyramid now that you have the height (which is b)

V = a^{2} \frac{h}{3}  \\\\V = 20^{2} * \frac{24}{3} \\V = (400)(8)\\V = 3200 cm^{3}

V = 3200

I hope this helped! :)
