  1. If I understand the definitions correctly,
    "surface area" would be the total of all the areas of an object, while "lateral" surface area would exclude the base

    so the surface area of a square pyramid
    = area of the square base + 4(area of the triangle)

    That's my "formua".
    In both #1 and #2 you then give dimensions H, W, and L without defining them. If the base is square, how come we have different (W)idths and (L)engths

    in #3 Diameter = 8, thus radius = 4
    height = 7
    Thus slant height of cone = √(4^2 + 7^2) = √65
    surface area = πr(r+√(h^2+r^2)
    = 4π(4 + √65) = appr 151.58

    or surface area = πr^2 + πrs, where s is the slant height
    = π(16) + π(4√65) = 151.58

    I got the same answer using 2 established methods, none of the answers given match that.
