    Okay. The surface area of a square pyramid is a square and 4 triangles.

    First, find the area of the square:

    5*5=25

    Subtract the square from the entire surface area:

    175-25=150

    Now, we know that the area of the triangles added together is 150. Since there are 4 triangles, we want to find the area of one triangle:

    150/4=37.5

    Now we can set up an equation to find the slant height (or the height of the triangle):

    1/2*5*h=37.5

    5h=75

    h=15

    The slant height is 37.5 inches. Sorry for the long answer!
