No answer choices given....<br>
The area of each of the four lateral faces is 350/4 = 175/2 square meters.  With a slant height of 25m, the side length of the square base is 7m.<br>
The foot of the altitude of the pyramid is in the center of the square base, 3.5m from each side of the base.<br>
The height h of the pyramid can then be found as the length of the other leg of a right triangle with hypotenuse 25m and one leg 3.5m.<br>
Then the volume of the pyramid is {{{V=(1/3)(7^2)(h)}}}<br>
